A Gift for Gardeners

"Engaging speakers." "Wonderful ideas.""Great giveaways." "Fabulous food."

That's what gardeners had to say about last year's first-ever Outdoor Living Extravaganza events in Chicago and Boston. This year Proven Winners is bringing this enjoyable and educational gardening seminar to additional cities across North America.

You'll learn from experts about creative new ways to use color, the easiest ways to grow plant varieties, how to put together exceptional containers, and much more.

P. Allen Smith, The Today Show’s gardening expert, will be at some locations with fun and practical advice, and later you can join him for book signings and photos.

In addition, you'll be treated to a goody bag of exciting gifts-including a plant; you'll enjoy delicious lunch, beverages, and snacks; and you'll have plenty of chances to win great prizes.

What People are saying ......

I attended your PW seminar in Chicago, this weekend. Loved it! It was a wonderful day! Thank you!Nancy from Wisconsin

I was at your Chicago show over the weekend and I would like to compliment you on a great time! All of the speakers were wonderful and I really learned from them. I would love to attend another show! I just wish it wasn't winter in Chicago I am ready to attack the yard! Thank you for an enjoyable Saturday! Kathy from Illinois

My husband and I were among the fortunate gardeners who attended the Outdoor Living Extravaganza in Chicago yesterday. Thank you, thank you, thank you for an inspiring, fun, and informational day. We've been serious gardeners for over 40 years and have never experienced a garden seminar that could even come close to the experience you provided. We hope this will become an annual event. Again, thank you for a wonderful day. Kim from Wisconsin

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.

New Plants: Netherlands 09

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.
