Snow Day Surprise - Pearlbush Reinvented

I was just walking in our test garden and was lucky enough see Snow Day Surprise Exochorda (Pearlbush) in bloom. Surprisingly, Pearlbush is not a well-known shrub. It is hardy, heat tolerant and easy to grow. It has showy, white, pearl-like buds in the spring that give it its name. An older cultivar, Exochorda x macrantha "The Bride" caused issues for many growers due to propagation difficulties and the tendency for young plants flop- especially in a container at retail.The plant is quite elegant in the garden once mature, but as a young plant on the nursery it is difficult to train into a salable plant. Enter Herman Geers, the plant Dutch breeder that developed Wine & Roses Weigela.

Herman, like other growers, was tired of trying to grow "The Bride", so he set out to develop a better Pearl Bush. Due to the smaller size of European gardens, he set out to create a smaller, more compact plant that could look good at a young age and was easy to propagate. In 1994 Herman crossed "The Bride" with Exochorda racemosa, an upright species with large flowers. For the next 10 years he evaluated his seedlings culling out all but the best-looking plants. He conducted propagation trials on his best plants and narrowed the field down to 5 with the best rooting percentages. From breeding to evaluation, the entire process took sixteen years, and out of the five best plants, he ultimately selected Snow Day Surprise. 

Snow Day Surprise starts flowering in early April or May depending upon where you live. At first the plant is covered with hundreds of pure white pearls - the buds - which last for about 3-4 weeks. The pearls then open up into large, pure white flowers which can last another 2-4 weeks. It is hardy from zone 4 to 8. The habit is more upright than "The Bride", but matures into a compact mounded plant around 3-4 feet tall and around 4 feet wide. Like Quince, (Chaenomeles), it makes a nice splash in the spring garden.

We started selling liners (young plants) this spring, so you can expect to see plants hit the retail market over the next year or so.

--- Side Note ---

People have been emailing me that their Plant Hunter emails have looked a bit funky as of late, with the text running over the pictures. I had switched to a new version of Blogger called "Blogger in Draft," as it was suppose to work better with videos. I have since changed back to the old Blogger - so I trust that this post arrives in good order. I apologize for any previous posts that were of poor quality and I hope that I have taken care of the issue. If not, please let me  know. As always - I appreciate your comments, and your continued interest in reading The Plant Hunter.

Double Take Quince - NC State Does it Again

Europe use to be the the hot bed of shrub breeding, but not anymore. Sorry guys - but it's been relocated to Mills River in the beautiful Blue Ridge Mountains of North Carolina. Tom Ranney and his crew at the Mountain Horticultural Crops Research and Extension Center, Darren Touchell, Tom Eaker, Joel Mowrey, Nathan Lynch, Jeremy Smith and Kevin Parrusfor are a well oiled breeding machine that continues to develop one great new plant after another.

This is the team that broke the color barrier with the introduction of the first ever pink flowered Annabelle Hydrangea - Invincibelle 'Spirit'.

Now they've developed a series of quince (Chaenomeles) that look a lot like Camellias, but much hardier, called the Double Take Series.

Double Take 'Orange Storm'

Double Take 'Pink Storm'

Double Take 'Scarlet Storm

As you can see from the images the flowers are very large and have lots of petals. The color range is blessed with deep hues of scarlet, pink and orange. To make life even better they're thornless! While quince is an old fashioned shrub that is not as popular as it once was, I suspect these plants are going to reinvent this old time favorite, and make quince popular once again.

  

I love quince as it is a nice change from the typical spring flower color we get from Forsythia. The colors are rich and warm you up on a cool spring day and get you pumped about being out in your garden. These plants make a very colorful hedge. I think quince is at its best trained up a wall to show off its flowers at eye level. It's also a great cut flower and makes a very elegant show in a vase. These are very new plants, just like a lot of plants you will see on my blog, so they're not generally available at retail. There are a few mail order nurseries that have them this year, but you can expect to see them work their way into better garden centers over the next few years.

We have been trying to get them approved for Canada, but the at this time we have not had any luck with the Canadian government. Hopefully this will change soon.

Bloomerang Lilac Starts a Controversy

Who would have thought that Bloomerang® Purple Lilac (Syringa ‘Penda’ ppaf) would create such a controversy? First Slate magazine comes out with an article entitled “Gilding the Lilac: A new hybrid could kill the nostalgia...” and then MaCleans Magazine follows up with an Internet article titled the “Ever-blooming Lilac Wars.” It seems that some people feel a lilac should bloom only once and only in the spring. I disagree and so do the thousands of people that rushed to buy Bloomerang when Better Homes and Gardens magazine did a limited release in March of 2009. Expecting to sell just a thousand plants, BH&G sold over 11,000 plants and turned away a throng of disappointed, potential buyers.

Bloomerang Lilac is not the first reblooming lilac. In 1917 Charles Sargent of the Arnold Arboretum noted that Syringa microphylla (S. pubescens subsp. microphylla var. microphylla) “… if it keeps up its habit of flowering a second time in autumn it will be at least interesting even if other lilacs are more beautiful. In her 1928 book “Lilacs” Susan McKelvey noted that S. microphylla has “… the curious habit of blooming twice in one season.” Syringa ‘Josee’ (syn. MORjos 06F) a small leafed, pale pink flowered cultivar introduced in 1974 by Minier Nursery of France is another noted remontant lilac. ‘Josee’ is a complex cross (Syringa pubescens subsp. microphylla x Syringa pubescens subsp. patula (syn S. velutina) x Syringa meyeri subsp. meyeri) developed by Georges Morel. More recently, Frank and Sara Moro of Select Plus International Nurseries of Quebec, Canada introduced several reblooming cultivars. So why all the fuss about Bloomerang lilac?


There are a number of things that have put Bloomerang in the spotlight. From my observations, (and a good many of the 400 garden writers that trialed the plant) it is the most consistent and prolific remontant lilac to date. The initial bloom is heavy and appears in mid-May. It goes through a rest in June and then begins to rebloom in July and continues on until frost. While the summer and fall panicles are not as large as those in the spring, it puts on a very good show. Every single branch bears flowers (not just an occasional flower). One of the reasons for its propensity to flower is its strong growth. As long as it continues to grow it continues to produce new flowers. You don’t have to prune it get it to rebloom, however, a light shearing after the initial bloom results in a fuller plant with more branches and thus more blooms.

As far as its ability to bloom and rebloom I have no doubt. In the selection process, I tagged only the seedlings with the most prolific summer bloom. Each year I repeated the process and in the end I chose the three plants with the most tags. These three, strongly remontant selections, were then propagated and evaluated further in production and in the garden. Eventually we selected one plant and introduced it as Bloomerang Purple. Of the remaining two plants, one appeared special enough to introduce and should be out in a few years. 

Our Lilac breeding program continues on. I have sowed out F2 crosses and have selected five more remontant plants of various shapes and colors. I have also made crosses that draw in new genetics to obtain plants with dwarf habits, glossier foliage, better fall color and larger flowers. Many of these plants look promising but only prolonged testing and evaluation will determine which, if any, are worthy of introduction. But the plan is to offer a range plants under the Bloomerang series.


As the Product Development Manager at Spring Meadow Nursery, one of my main functions is to find new and superior plants for the Proven Winners flowering shrub line. The shrubs in this line are selected based on a specific criterion that in its most general terms focuses superior performance, improved disease resistance, ease of production and culture, compact and dwarf habits, attractive foliage, and extended or multiple seasons on interest. Adding lilacs to the line was a goal of mine because they offer many fine attributes that make them popular. Most notably lilacs bloom in the spring when people are in the garden center, they offer excellent hardiness, they’re well recognized by consumers, they’re very colorful in bloom and they offer fragrance. On the other hand lilacs typically offer only one season of interest and are susceptible to Powdery Mildew and Pseudomonas. Bloomerang addresses all of these issues and as a result is off to a very good start.


Still, I’m not sure why Bloomerang or any other reblooming lilac is so controversial. It seems to me that some people like to complain and to create controversy even where is there is none. I guess it helps them sell magazines and attract blog subscribers. Regardless, it’s strange to read comments like “ Of all the things that plant hybridizers could be focusing on, this type of indulgence is a waste of creativity… (GardenRant.com, August 9, 2009 “How much plant improvement can we stand?”). How can I respond except to say go ahead and call me indulgent and blame me for ruining the joy of lilacs. It will only sell more plants and beautify more yards.

Sky Miles for Sky Pencil: The Journey from Mt. Daisen to Maryland

You migth suspect I do a bit of traveling – but plants have a funny way of traveling around the world too.

Sky Pencil, Japanese holly, (Ilex crenata) is a plant that has earned some serious sky miles. This narrow, column-like, evergreen holly was discovered in the wild on Mount Daisen, Honshu, Japan by my friend Akira Shibamichi. He then passed it on to his good friend, and my acquaintance, Dr. Yokoi, the noted variegated plant collector. Dr. Yokoi passed it on to Rick Darke (the ornamental grass guru) while he was in charge of research at Longwood Gardens in Kennet Square, Pennsylvania. (I met Rick while I was a summer student at Longwood in 1982). Rick got the plant in 1992 while on a plant collecting trip to Japan with Sylvester March of the United State National Arboretum. The USNA then propagated it and introduced it and now it’s grown by nurseries and gardeners across the U.S. and around the world.

Just to keep the story going, Mike Farrow of Holly Hill Farms nursery in Earlville, Maryland took ‘Sky Pencil’ and crossed it with a male selection of Japanese holly. His goal was to develop a very narrow, conical holly with dark green leaves. You see - vertical Plants, especially those with the quintessential Christmas tree shape are very popular, Thuja occidentalis (aka arborvitae, aka Eastern cedar), Skyrocket Juniper and Dwarf Alberta Spruce (Picea glauca ‘Conica’) are all narrow, pyramidal varieties and nurseries grow them by the acre. Mike Farrow understood this. Successful plant breeding starts with a good eye for plants and a good idea and Mike has both. (His impressive plant portfolio includes Arctic Fire Redstem Dogwood, 'Sienna Sunrise® Nandina, Bollywood Variegated Azalea and Pink Panther Echinacea).

After growing out hundreds seedlings, Mike selected out the six best plants to propagate and to evaluate further. Part of this evaluation took place in Michigan after Mike sent his six holly selections to Spring Meadow. For our part of the evaluation, we propagated and grew on about 1,000 plants of each selection. We evaluated each variety in propagation, as a one gallon crop and then as three gallons to gain a thorough understanding of it production and timing. To better understand how the plant performed in the garden we planted the hollies out on two different test gardens. Eventually we choose the best looking, best performing plant of the bunch. At this point we sent plants to about thirty growers across the country to find out how the plant performed under various climates and soils. Ultimately, after all these evaluations we took the leap and introduced Mike’s new plant as Sky Pointer Holly (Ilex crenata ‘Farrowone’ pp# 20,049).

Sky Pointer Holly has shiny, flat, dark evergreen leaves. The flat leaves make for hard living for spider mites, as they cannot hide and protect themselves under the cupped-shaped shaped leaves which are common on Japanese holly. This gem has tight, upright, conical branching which makes it a great container plant. I see many such plants used in sidewalk cafes and near store fronts for decoration. It’s hardy to zone 6 and just like ‘Sky Pencil’ it appreciates a bit of shade, especially in the winter. Growers appreciate its narrow growth habit. Narrow plants require little or no spacing in the nursery, which ultimately saves them time, labor and money.

And thus the journey continues. Last year, Spring Meadow Nursery shipped Sky Pointer liners (starter plants) to wholesale growers across North America. These growers pot them up, and grow them on for one or two years and then send them on a truck to a garden center near you. If all goes as planned, someone will buy a Sky Pointer holly. Perhaps it will be you. And after you plant it in your yard and watch it grow, I suspect you’ll think about its long journey from Honshu, Japan to your front yard.

White Dome Hydrangea is not Gaudy - But It's a Great Landscape Plant

Felder Rushing - A Simple Dirt Gardener

I've known Felder Rushing for about eight or ten years. I see him at garden writer conferences. He's easy to notice and hard to forget with his beat up hat, scraggily goatee and his standout Southern accent. I knew he was a successful writer and that he wrote books and that his articles were published in fancy magazines that actually paid him money. I also knew he has a garden growing in the back of his F-150 pickup truck. But until Felder was booked to speak in my home town of Grand Haven, Michigan and I read an article in my hometown paper – I didn’t know how little I knew about Felder.

I did not know that Felder is a self-proclaimed dirt gardener. What's a dirt gardener you ask? Well this is how Felder describes himself:

"I garden for the love of it — not for the challenge of it. I have one basic gardening rule Green side up. Dirt gardeners don't do soil prep — we plant stuff in the dirt. We know a ceramic gnome is just as valuable as a life-size marble naked goddess statue, and that birds are just as interesting as anything out there and they don't ask much of us." He says, “... a plant shared with a friend is as valuable as one ordered from a glossy catalogue. We know where our plants came from — even the ones we stole."

Because Felder gardens in the heat of Mississippi, and I garden in the great white North, I assumed we had little in common. But I was wrong. It turns out we share the idea that gardening and growing plants is fun and simple. So simple that anyone can do it.

The big problem, in my opinion, is that there are way too many expert horticulturists out there telling you how complicated it is to garden. They would have you believe you need to match your flower colors using a color wheel. They say you have to sequence the bloom time of your flowers and to use grey as a foil between red and orange. They'll tell you to double dig your flower beds, do a soil test and to adjust your pH. (I’ve never done any of these things). And of course they'll tell you to “buy my book” to know how to garden.

This is all phooey.

You do not need the help of garden experts to garden. You just have to dig a hole and put a plant in it and water it a bit. Get over the idea that every plant you plant has to live 100 years. Plants are living by definition so of course they die. Just plant it - and don’t take it so personally if it dies. I’ve got a master's degree in horticulture and I've killed hundreds of plants. I'm ok with that. That’s how you learn!

It’s not about you!

When a plant grows well in our garden we say “Look what I did!” And when a plant dies we say “I have such a brown thumb.” Either way we give ourselves way too much credit. The fact is the plants is doing the growing – not us. So dig a hole, put a plant in it and enjoy it. If it struggles or gets too big for it's spot – dig it up and move to another location. If it dies - dig it out and plant something else. If it thrives - enjoy the miracle that plants are living creatures that hang out in our yard.

Growing plants is fun. It’s wondrous. It’s addicting. It’s good for the soul. It’s dirty, yet at the same time it brings us closer to God. It’s suppose to relaxing, so drop the guilt and stress that comes with doing it right or wrong – and just do it.

Felder Rushing is the author or co-author of 15 gardening books; and countless newspaper columns and articles for publications such as Horticulture, Landscape Architecture, Better Homes & Gardens, Fine Gardening, and National Geographic. Felder has been featured three times in full-length articles in the New York Times. He has hosted a television program that was shown across the South, and appeared many times on other TV garden programs. Felder currently co-host’s a call-in garden program on NPR affiliate stations called The Gestalt Gardener.

Abracadabra Hydrangea

Regular people look at plants quite differently than your typical horticulturist. That’s why I get a kick out of reading comments by Mike Dirr where he gushes about the attractiveness of the bark on some particular shrub. As if the typical homeowner is going to actually crouch down under a shrub and exclaim “Wow, now that’s awesome bark.” From my experience, the public does not get overly excited about bark (that is unless it has in-your-face bark like a Paper Bark Birch).

I get excited about bark, but I have to remind myself that most people won’t even notice. Hydrangea macrophylla ‘Nigra’ (Syn.: H. macrophylla 'Mandshurica') is a good example. It’s a cool plant. I like it but it’s never been a big seller. It has very attractive back stems, but the feature is obscured by the leaves, so few people ever notice.

When I first saw the Abracadabra Series of Hydrangea in Germany, I got so excited I could hardly contain myself. That’s because, for the first time ever, I actually felt that the average shopper could get excited about bark. What makes these plants so unique is that they have internodes (the spacing between the leaves) that are large enough to give you a real good view of the dark, glossy black stems. Of course it doesn’t hurt that the plants also have funky blooms that are both massive and richly colored. I honestly think that these plants have a cool factor that will make them as popular as lucky bamboo. As a pot plant they would make great centerpiece on a table. You’d actually be able to see the person across the table from you.

Abracadabra Star has massive lace-cap blooms with hot pink flowers. The stems are straight and strong.

Abracadabra Orb is a mop-head hydrangea. The flowers emerge a blend of peach and green then mature to a deep pink. As with Abracadabra Star, the bloom size is massive. The sepals are thick in texture and again are held up on strong, upright stems.

Cool Conifers

The great thing about dwarf conifers is that they require so little work to keep them looking so good. Just plant them and enjoy them. They add color and structure in the winter months. I like varieties that add interesting color or texture as they stand out in the garden. Here are a few of my favorites.

Thuja plicata 'Gruene Kugel' is a great little Western cedar. It requires little to no pruning and it has very nice shinny foliage and dark color.

Thuja occidentalis 'Linesville' is a soft, rounded, juvenile plant discovered by Joe Stupka of Pennsylvannia. Also sold under the name Mr. Bowling Ball.

Juniperus horizontalis 'Gold Fever' was introduced by Iseli Nursery. A colorful, low growing plant that benefits from dappled sun.

Chamaecyparis pisifera 'Little Keon' in a small rouned plant with foliage similar to 'Boulevard.' Blue foliage is always a great additon to the garden.

Thuja plicata 'Whipcord' is a very cooling looking shrub. The species has good deer resistance.

This is just one of the funny, sheared conifers that can be found at Iseli Nursery. While I'm not into shearing plants myself, you have to respect someone that can do it this well. It does make you smile.

Caryopteris is not a Spiraea

It is unfortunate that Caryopteris has the common name of Blue Spirea for it is not a Spiraea and it’s just plain confusing. How this came about I do not know as they are not even in the same family; Spiraea is in the Roseaceae family while Caryopteris is in the Verbenaceae family.

The genus Caryopteris is comprised of roughly 15 species, most being native to Asia. Only are few of these species are grown in North America as ornamentals. The majority of the ornamental selections sold here are hybrids; Caryopteris x cladonensis (pronounced Cary-op-ter-is clan-don-en-sis) which is a hybrid between Caryopteris incana and Caryopteris mongholica. Unless otherwise noted, the following information here after refers to this hybrid.

Caryopteris is a fall flowering shrub with rich blue to purple-blue flowers. While it is hardy to USDA zone 5, it is typically a die-back shrub in the North, behaving much like a Buddleia. While the plant makes woody stems, they are tender and die back during the winter. As the plant grows back quickly in the spring and its flower buds (and flowers) are formed on new wood so the plant does not miss a beat.

Culturally there are three things necessary to grow a nice plant. First off, it loves full sun. It will grow in partial shade but it will not look happy or flower nearly half as well as a plant in full sun. In addition, the yellow leafed cultivars have much better color in full sun. In partial shade the leaves will appear a dull, washed out green. The next thing to know is that Caryopteris needs well drained soil. It will not tolerate heavy, wet clay soils, or at least not for long. People often blame the plant for not being winter hardy because their plant did not make it through the winter, but the real culprit is wet soil. Well drained soil is a must. Once established Caryopteris is very drought tolerant and requires even less water. My final bit of cultural advice deals with pruning – as the plant typically dies back in the winter, you should only have to prune the plant once and that is in the spring after the plant starts to grow. Simply cut the plant back to wood with active sprouts. If you wish you can give the plant a slight shearing in early summer to bulk of the body of the plant. Fall pruning is not recommended, as it stimulates the plant to grow when it should be going dormant - the result can be a dead plant the following spring.

Caryoteris is a wonderful garden plant because it offers a mass of colorful blue flowers in late summer when few other plants are blooming. It’s a great source of pollen for bees and butterflies. Its aromatic foliage is turn off to deer so it rarely bothered by Bambi and her four legged friends.

There has been a flurry of Caryopteris breeding over the past 15 years and we have never had such wonderful plants for the garden. Here are a few of the newest cultivars to hit the market.

Petit Bleu (‘Minbleu’) is one of my favorites as it is a semi-dwarf plant with very tight branching and a nice mounded habit. The flower color is a very dark blue and the foliage is very dark and glossy which makes a great background for the flowers.

Sunshine Blue (‘Jason’) is a yellow leafed form of Caryopteris incana. It is a larger plant than most (3-4’) with masses of clear blue flowers that appear a bit earlier than other varieties. This English selection has very good hardiness and is more adaptable to heavier soils. It was a vast improvement over ‘Worcester Gold’ which can look a bit ratty by mid summer.

Lil' Miss Sunshine ('Janice') is new variety that I hybridized using Petit Bleu and Sunshine Blue. This plant has be best attributes of both parents as it is hardy, compact with glossy bright yellow foliage. The abundant flowers are a rich clear blue. It should be available in summer of 2010.

‘Sterling Silver’ is a new selection from the renowned English plantsman Peter Catt. It is a silver leafed selection that will most certainly replace 'Longwood Blue' once it is more widely available.

There has been a rash of variegated forms released in the last few years. Two of the better looking plants are ‘Summer Sorbet’ which has green and yellow leaves, and ‘White Surprise’ has silvery-green leaves adorned with a thin cream margin of variegation. As with most variegated plants, these will throw the occasional non-variegated shoot. Simply prune and remove these shoots as they appear

Dr. Shim - The Mike Dirr of Korea

Some of you may have read one of my older posts on plant hunting in Korea. It was one of my greatest adventures and it explains how I met Dr. Shim. Well Dr. Shim just spent three days with me at Spring Meadow Nursery. He came to see some of his new Hibiscus syriacus selections that we are evaluating for potential introduction. Dr. Shim developed Lil’ Kim Hibiscus – the first dwarf rose of Sharon. This is a great little shrub that unfortunately is still hard to find. If you can find it give it a try!

I like to call Dr. Shim the Mike Dirr or Korea. For roughly 30 years he was the Professor of Ornamental Horticulture at Sungkyunkwan University, in Suwan just outside of Seoul. Just like Dr. Dirr, Dr. Shim has roots at the University of Illinois. This is where he got his Ph.D., and where spent a year as a visiting professor. He is now retired and spends his time golfing and breeding Hibiscus, Forsythia and Korean Tiger Lilies.

Dr. Shim got into horticulture as a young boy. His family owned a pear orchard. He told me that one of his first jobs was bagging pears. In Korea, pear growers bag the fruit while still on the tree to protect them from insects and disease. Ten women would make bags out of old news papers and each tree would require up to 500 bags. You can image it took a good deal of time to bag every pear in the orchard yet this did not dissuade Dr. Shim from continuing on in horticulture. He went on to study post harvest physiology, just as I had. After working for three and a half years on his Ph.D. in Champaign we retuned home to teach pomology in Korea. In time, his position was changed to ornamental horticulture. The rest is history.

While traveling, looking for new plant is great fun; it’s also a pleasure when breeders come to visit me. We spent two days touring the nursery, looking over new plants, scouting the seed beds for treasures and most importantly evaluating his 20 or so cultivars we have under evaluation. I’m happy to report there are many fine plants and I suspect a few will make it to market in the coming years. The hard part will be narrowing the plants down to the best three or four cultivars. His dwarf Hibiscus selections look great and have the potential to widen the Lil’ Kim line with a broader color range.

As I’ve said before I have a great job. I get to see really cool plants long before anyone can buy them. But the best part of my job is meeting the special people that develop these plants. Dr. Shim is more than just a special plant breeder. He' is a special friend.

I just got back from a week in the Netherlands looking at new plants. Here are a few that I found interesting. Which do you like?

This is a greenhouse bench filled with Lo & Behold 'Blue Chip' Buddleia. It will be introduced in Europe next spring. I've never seen so many butterflies in one place in all my life. The Boskoop Royal Horticlture Society has it awared it a gold medal.

Chasmanthium 'River Mist' is acutally an American plant but it won a Gold Medal from the Boskoop Royal Horticulture Society. It was developed by Itsaul plants.



Echinacea 'Irresistible' is just one of may new Coneflowers on the market. Below is a vase shot of one assortment now on the market.





This is a new larged variety of Hibiscus moscheutos called GH7 or Guido Oak Red.

This is one the the best red leafed grasses I've ever seen. It's not hardy but can be used as an annual in the North. It's called Pennisetum setaceum 'Fireworks' and I love the contrast with the green interior leaves.

Pretty Much Picasso petunia is available here in the US but it has made a big splash in Europe as well. It won a metal from the Boskoop Roayl Horiculture Society for one of the best new plants for 2009.

Invincibelle Spirit Hydrangea Video

I just bought a flip video recorder. What a great little device. This is my first attempt in using it - I suspect I should be using a tripod but I was very excited to use it and share with you what's looking good in the garden today. I've shared pictures of Invincibelle Spirit Hydrangea before but video seems to give you a better idea of what the plant looks like. If you have a blog or a website you might consider a flip. It films in HD and is very reasonably priced. Best of all it's easy to bring along so you're more likely to use it. Check out the quality of this video.

As for the Hydrangea, it will be available at better garden centers in spring of 2010. We're pretty excited about the plant. It appears that the flowers are larger than anticipated. We're also excited that the plant will help raise money for the Breast Cancer Research Foundation.


If you're a garden center retailer, think about how you can utilize this plant to raise even more money for breast cancer research. This spring Chalet Nursery and Garden Center featured this plant during their spring workships. They raffled off plants and donated the proceeds to the BCRF. Fruit Basket Flowerland did the same. The Morton Arboretum auctioned off a plant for $1,600. What could your garden center do for this great cause? Get your staff together and make a plan for next spring.
