The Golden Age of Plants and Technology



truly believe that we live in the Golden Age of technology and gardening. Just think about it. With inexpensive flight, we now have access to plants from around the world.  With the formation of the European Union and the unification of plant patent laws, plant breeders can now make a living developing new plants - and we benefit from lots of new plants.  With the creation of the internet, Pinterest, and e-Harmony we can connect with gardeners and plant geeks around the world.  With Wikipedia, the Plant Hunter blog and GardenWeb we now have access to the most massive library of gardening information right at our finger tips.  And with a wide array of garden centers, online mail order nurseries and QVC we can buy just about any plant we want with very little effort.  What a great time we live in!

The Lo & Behold Series butterfly bush  


And if you're amazed at how the phone has changed in the last 20 years from the big, black Bell and Howell to the itty-bitty iPhone, consider what has happened to the big, bad butterfly bush. The once large, rangy, seedy shrub is now a cute, cuddly compact shrub sans seeds that reblooms without dead-heading. 


Lo & Behold 'Blue Chip' opened up new ways to use butterfly bush
    

While Steve Jobs had the vision for the iPhone, Dr. Dennis Werner had a vision for a new breed of Buddleia. His vision is Lo & Behold - a brightly colored series of dwarf butterfly bush and just like the iPhone his vision is now reality.  To the casual observer the iPhone and the Lo & Behold series might seem to be overnight success stories, but both inventions took years of testing, trialing and hard work to create. Greatness takes time, but in the end it's worth the wait; both inventions are now praised by critics for their award winning low profile and superior aesthetics.    

Lo & Behold now comes in white with 'Ice Chip'

But there are also many differences between the iPhone and Lo & Behold butterfly bushes. Unlike the iPhone which has been criticized for containing dangerous chemicals, the Lo & Behold series is an environmentally friendly series of seedless selections that are non-invasive. These plants will not hurt the environment. Unlike the iPhone which is produced in China, Lo & Behold is grown locally. And instead of releasing greenhouse gases these little guys sequester carbon and emit pure oxygen. You can grow these shrubs without any guilt. It's even better for the earth than driving a Prius. Honest.

From a health standpoint you need not worry about microwaves and the potential for brain tumors with the Lo & Behold series.  Rather, it is well documented that using these and other plants have many positive health benefits


Lo & Behold 'Purple Haze dwarf butterfly bush
But perhaps the best thing about the Lo & Behold series compared to the iPhone is that these beautiful new plants are a much better value.  These cool new butterfly bushes may cost a tad more than the old models, but they cost substantially less than the $200-$400 that an iPhone will set you back.  And while the iPhone is obsolete within a few short years, these little beauties will get better with each passing year.  The fragrant flowers bloom non-stop from mid-summer right up until frost without any need to dead-head the old flowers.  Just give them a small charge of slow release fertilizer in the spring and they're good to go for an entire year.

There are lots of great new apps for Lo & Behold 

Many early adapters rave about all the new apps for these little shrubs.  Their petite size allows you to use them in containers, around decks and even as a ground cover. Some people have reportedly used them in mixed hanging baskets. The apps are endless! And while you do not get Angry Birds with the Lo & Behold series, you and your kids will love the happy hummingbirds and beautiful butterflies that come free with every Lo & Behold purchase.  

                    This is awesome. I need this!                          


Jelena de Belder – Her Plants Live on


The hydrangeas (Hyd. paniculata) were in full bloom when Dale and I met Jelena in the summer of 1996. We met her at Hemelrijk, her family estate near Antwerp, Belgium. As she shuttled us about the grounds in her beat up VW Rabbit, filled with pots, shovels and plants, we soon realized we were in the presence of someone special. Her every word was filled with passion.  With the pride of a mother she introduced us to the hydrangeas she and her husband had developed; ‘Pink Diamond’, ‘Unique’, The Swan, ‘Burgundy Lace’, ‘White Moth’ and her personal favorite ‘Little Lamb’. “This is a very special plant,” she told us, “Little lambs dancing about in joy. Very special.” 

On another visit, we had arrived at the peak of the witch hazel bloom. The DeBelder’s had been collecting and breeding witch hazels for over 40 years and they had hundreds of plants under evaluation scattered about the estate. The cool foggy air was saturated with the sweet smell of witch hazel blooms. Under towering beech trees (Fagus sylvatica) we walked her estate and across the last fleeting patches of melting snow. With amazement we gazed at the rich and diverse colors of those spider-like blooms; yellow of course, but also various shades of orange, red and even purple! A farmer with his Belgian draft horse, steam shooting from his nostrils, crossed our path to complete the most perfect picture. Dale and I looked at each other as if to say “Could life be more perfect?”


Our trips to Hemelrijk were always magical. Her passion for plants and her passion for life were heartfelt and contagious. If you shared this passion, Jelena was your friend. Not just a casual acquaintance, but rather, it was as if you had known her since her youthful school days in Slovenia. Once, I had the pleasure of bringing my wife Tracy to Hemelrijk. For years I had shared my stories of Jelena and her plants, but now she would live them first hand. It was a cool summer morning and Jelena, dressed in a bathrobe, greeted us, hugged Tracy and promptly handed us a basket of peas to shuck while she dressed. No need for pretense, we were among friends. Soon afterwards, Jelena took Tracy by the hand and led her through the garden, sharing her love for each plant along the path. Watching them together it was hard to believe that they had just met that very morning.



To the end, Jelena remained youthful. Almost exactly five years later, we received word that Jelena had died while swimming in the Adriatic Sea. She was 78 years young. Memories flooded back is a rush; the taste of her rose petal lemonade, sipping homemade pear wine, and the rich taste of Belgian chocolate and strong coffee shared together sitting by the fireplace after a long garden walk. I recalled my excitement at seeing the original ‘Unique’ hydrangea and the original ‘Diana’ witch hazel and standing side by side with the person that brought  these lovely plants into the yards and gardens of the world.    


I wish that I could take you to Hemelrijk, to meet Jelena, just as I had taken Tracy there. I am certain that Jelena would have made you feel special. She would have willed you to appreciate the beauty of every plant along the garden path. But I cannot. So we must be content with her legacy; the beauty and magic of her plants; a gift to gardeners everywhere. Her plants live on, and so Jelena lives on too.

A Good Idea and a Bit of Luck


Plant breeding starts with an idea. The idea is based on experience in the garden and by asking the rhetorical question – “Wouldn’t it be great if …….?”  In the case of Annabelle Hydrangea (Hydrangea arborescens ‘Annabelle') the statement would be - “Wouldn’t it be great if Annabelle had pink flowers?” or “Wouldn’t it be great if Annabelle had strong stems?”

Some ideas are unique and obscure, while others are quite common within the community of gardeners and growers. I suspect that anyone that has grown Annabelle hydrangea has had these same thoughts. But to make it happen you have to act.

The next step in plant breeding process is to determine if there are any other plants (cultivars, varieties or species) that can be utilized in the breeding process to bring in the traits you’re looking to incorporate. If that other plant(s) exists, and if the chromosome number is compatible, then you go to work.

Dr. Tom Ranney and Richard Olsen at NC State each thought it would be great if Annabelle had pink flowers and the end result was Invincibelle Spirit – the world’s first pink Annabelle hydrangea. Of course it took years of hard work, but the process was greatly helped by a bit of luck; Olsen discovered the perfect breeding partner for Annabelle. While hiking in the Blue Ridge Mountains, Olsen discovered a Hydrangea arborescens with pink, lace-cap flowers which he named Wesser Falls.'  This was the key ingredient in creating Invincibelle Spirit.

Invincibelle Spirit Hydrangea

An Annabelle hydrangea with strong stems has been on everyone’s wish list since the plant was first put into cultivation by Dr. J. C. McDaniel in 1962. The wish came true in 2009 with the introduction of Incrediball Hydrangea. The story of Incrediball begins with White Dome Hydrangea (H. arborescens ‘Dardom’). White Dome was discovered by Wout Kromhout in a batch of seedlings at Hemelrijk, the estate of Robert and Jelena de Belder in Essen, Belgium. White Dome hydrangea is a beautiful plant with large, white, lace-cap flowers and thick, sturdy stems. It was the perfect breeding partner in my quest to create an Annabelle hydrangea with strong stems.  This was my first bit of luck.

White Dome Hydrangea

The next bit of luck appeared when we grew out the seedlings from our Annabelle x White Dome cross. While there was a good many seedlings with thick strong stems and mop-head flowers, one plant stood out among all the others. This plant had flowers that were even larger than those of Annabelle. To my amazement, the flower heads that got even larger as the plant matured over the next three years.


Incrediball Hydrangea

Two new breakthrough plants and both were born with an idea and little bit of luck. 

So I’ll ask you. How would you finish the statement “Wouldn’t it be great if …….?”

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.

East to Grow Roses





If you subscribe to this blog than you now Dale and I visited with Chris Warner the Oso Easy rose breeder while in England. Getting to his Shropshire home was not easy even with a GPS unit. English addresses are a tad bit strange and the GPS does not like them. Thank goodness for cell phones!


Chris Warner in his rose breeding greenhouse


It was a great pleasure to visit with Chris and the get a better feel for how he breeds and selects his roses. For example - he leaves any diseased seedlings in his greenhouse seed beds so there is plenty of fungal inoculum available to infect and show which seedlings have the greatest disease resistance. We got to see all phases of his testing and selection. It is in the later stages in the process where Chris gets ruthless about culling out any diseased seedlings. Still even at these stages there are old rose plants near by to infect any susceptible roses.




One of Chris's most disease resistant roses in the Oso Easy line is a bright and cheerful red rose with a yellow center called Urban Legend. This rose is so healthy and floriferous it has been awarded the Lord Burleigh Award for Best Disease Resistant Rose, the Chauncey Beadle Award for Best Shrub Rose at the 2018 Biltmore International Rose Trials at the Biltmore Estate in Asheville, N.C. and the American Rose Society Award of Excellence. Now I have to be totally honest with you when it come to this rose. When it was time to name this rose, we considered several other names, including Barbed Wire, Brinks and ADT. These names may seen a bit strange, but you have to understand this is a very thorny rose, and because so it is perfect for planting under windows in high crime areas. There is a real need for security plants and the names were our attempt to position this rose for that very purpose. We settled on Urban Legend which speaks to it usefulness in fighting crime but also to its award winning disease resistance and flower power.

Chris has also made a name for himself with his hybrid Hulthemia Persica rose breeding sold under the series name Ringo Roses. Ringo Yellow is a magically colored rose with yellow, red pink and white in the bloom. His Ringo roses are substantially hardier and more disease resistant than anything else in the catagory. Ringo has proven it self by winning awards at the Hauge Rose Trials, first place at the Lyon Rose Trials and Gold at the Gold Standard Rose trials.

Ringo is sold under the Proven Winners brand in the USA



Ringo® Double Pink (Rosa 'Chewdelight), also a Hague Rose Trial First Class Certificate winner, comes with a fuchsia pink flowers, a dark magenta center and having 15 to 25 petals. It too has been a worldwide hit with rose growers.

Ringo Double Pink did excellent in our container rose trial

It is always a pleasure to spend time taking plants with a plant breeder, but it is even more so with Chris. He has such a depth of knowledge and such great enthusiasm for roses and it is evident in his plant introductions. They are smart and elegant. Beautiful, yet useful. Healthy, yet happy. I cannot wait to return to Shropshire, England!



Holly Reaches New Heights



I love the saying “Standing on the shoulders of giants” because it reminds me that most all great accomplishments are built on the people that labored before us. This is especially true in plant breeding.

Holger Hachmann, a plant breeder from the Holstein region of Germany is quick to remind people that his breeding work could not have been accomplished if not for his father and a housewife in Long Island, New York.

Holger grew up the son of a nurseryman and renowned plant breeder Hans Hachmann. His father was, without a doubt, the most prolific Rhododendron breeder ever. In addition to introducing hundreds Rhododendrons, he develop a number of popular Potentilla cultivars including Potentilla ‘Hachmann’s Giant.’ Plant breeding was taught to the young Holger by example, just as he learned to weed the fields and to root cuttings. Hans taught his son the secrets of plant breeding. His most important lesson was to start by identifying a problem or weakness in a plant, and then solve it. Certainly Holger was well trained and well equipped to begin his plant breeding career. He had a great teacher.

In stark contrast, years earlier a housewife was laying a new foundation. An amateur horticulturist by the name of Kathleen Kellogg Meserve, told a reporter "Not knowing what I was doing was an advantage. I didn't know what could be done and what couldn't. So I just did it." And without any formal training and without understanding chromosome numbers she develop what we now call Blue Holly. She crossed the beautiful but tender English Holly (Ilex aquafolium) with a hardy, low growing Rugose Holly (Ilex rugosa). At first glance this may seem trivial, but in actuality this cross made it possible for millions of people in Middle America to grow Holly.

And so the foundation was laid; Holger’s father had taught him the tools of plant breeding and Kathleen Meserve invented a hardy holly. And as blue hollies became more popular, Holger found himself growing a good number at his nursery. In time, he soon came to realize that Kathleen’s work was not yet complete. Growing a good quality blue holly took a lot of time and care. The plants grew slowly and required a lot of shearing to make a full plant. Additional people expected hollies to be upright pyramidal evergreens and not round bushes. Here was a breeding opportunity. To solve this problem, Holger crossed the hardy Blue Prince holly with ‘Alaska’ a pyramidal, glossy leaved English holly which was considered the hardiest of all English Holly.

With time and patience Holger made his selections and introduced two new plants. And fittingly, he named his plants Castle Hollies; stately, yet rugged plants built on a strong foundation laid down by two previous “Giants” of the breeding world. Growers in Europe and America have been growing his plants for about four years now and the reports have been very favorable. Castle Spire holly is fast growing female selection with bright red berries. It has a traditional Christmas tree shape. The foliage is quite unlike Blue Holly, being extremely glossy and rich green in color. Castle Wall holly is a very functional male selection. This is Holger’s favorite because it makes good container plant and a great hedge. Its dense, upright habit makes it a good replacement for the over used ‘Hicksii’ yew. With its useful shape and attractive glossy foliage, this plant is more than just a pollinator. It will find a home in the landscape as a specimen, hedge and foundation plant.

Castle Spire

Brick by brick, stone by stone and trait by trait, breeders continue to improve upon the work of their predecessors. Clearly it takes a strong foundation to build a beautiful castle that will stand the test of time.

Motorcycles, Lumberjacks and Rose of Sharon.



In the horticultural world, Dr. Roderick Woods has become famous for his Hibiscus syriacus (Rose of Sharon, Althea) breeding. But in his previous life, Woods was a world renowned physiologist, scholar and researcher at Cambridge University in England. His path to plant breeder was both unexpected and slow, but fortunately for us plant lovers it has delivered three of the most exciting new plants ever developed; plants with superior vigor that thrive both warm and cool climates and plants with large, unique new flower forms. This is Dr. Woods story:

Born in England during a time of war and growing up during post-war austerity, rather isolated in the country, Roderick Woods amusements centered on plants and animals. His family had a large vegetable and flower garden that provided the cash for extras like holidays. He was therefore drafted early into stone picking, pricking out seedlings and weeding. After school he wanted to go into forestry, but after a spell in a Salk vaccine tissue culture laboratory he was sent off, somewhat reluctantly, to train as a medical doctor. It was soon noted he had an aptitude for microscopy and interpreting structures, so he was diverted into research after his undergraduate degree. Woods earned his living for 32 years thereafter by teaching physiology and histology to medical and veterinary students.

In research he worked on nervous system structure with light and electron microscopes, the foetal development of the lungs and other topics in Oxford, Edinburgh and Cambridge. He then drifted into whole body human physiology and particularly temperature regulation. This research lead him into the esoteric field of accident and injury research and into the field of protective clothing. Most every fire-fighter, motorcyclist, horse rider, Police in riot situations, chain saw user, abattoir worker, fencer, and any other person that works in a dangerous profession, is safer today because of the innovations pioneered of Dr. Woods.

In 2002 Woods retired from teaching and research and moved to Norfolk to concentrate on Hibiscus breeding and running a protective clothing consultancy company, aptly named Blue Hibiscus Limited.

As a young child Woods had three Hibiscus syriacus (Rose of Sharon) plants in the family garden; red, white and blue. They grew slowly but were always appreciated when they flowered in the summer after almost everything else had finished. In 1974 Woods planted his first hibiscus plants in his garden near Cambridge. They never performed like the ones he saw on holiday in France and Italy; growth was slow and coarse and the flowers did not open well. The English climate was just not warm enough or sunny enough! This spurred him on to start collecting other selections on his travels.

It was in 1981, on his journey to plant breeder, that Woods had a life changing experience. He was in the south of France near Biarritz and happened upon an unusual pink Hibiscus plant growing in a roadside hedge that appeared to glow! Captivated by this glowing vision, he decided he must have this variety for his own garden. So upon retuning home to the UK, Woods began searching at local nurseries only to be told that no such variety existed. This led him to seek out and write various Hibiscus collectors all around the world, but again Woods had not luck. Returning to France for further holidays in the following years Woods searched for this glowing pink Hibiscus, but unfortunately the road had been widened and the plant was gone. He searched the local French nurseries and talked to anyone in the area that was growing Hibiscus but again no luck!

In 1988 his quest had lead him to discover a group of pink flowered Rose of Sharon plants that had grown in a near-wild state in some old gardens, farmyards and around churches in one area of the Pyrenees foot-hills. Woods reasoned that bees must have been at work and that if he wanted the true, pure pink Hibiscus he was going to have to be a super-bee. With permission from the locals Woods collected seedlings. The resultant plants were the beginning of Woods new obsession; Hibiscus breeding.

Initially, Woods breeding came with mixed success. He was not able to replicate the clear, glowing pink flowers he had seen in France, but he had discovered that his wild Pyrenees plants resulted in exceptional plant vigor and branching that he never seen before. Most Hibiscus syriacus breeding has its origins in very warm climates such as France. Many of the common cultivars in the US were developed at the National Arboretum outside of Washington DC. While most of these plants grow well in the South, they just don’t grow or flower as well in cooler, Northern climates. They certainly did not flower well in his Cambridge garden.

Woods, like most others that love Rose of Sharon, was fascinated with the cultivar ‘Blue Bird’. Who can resist blue flowers - but ‘Blue Bird’ is a strange bird; weak growing, poorly branched, course and short flowering. Woods wanted to develop a strong growing blue flowered plant an abundance of bloom. Over the years, Woods redirected his scientific skills that had made him famous in human physiology to breeding plants. He learned what to do and his breeding gave rise to very pure colors across the spectrum and plants with unusually strong flowing and growth.

Woods, of course is most famous for his Chiffon series of Hibiscus; exceptionally flowering plants noted for their large, flat single blooms with a lacy center. Until you grow these plants you cannot believe how unique they are in how they grow. While most Rose of Sharon are ridged and uptight, the Chiffons are finer in texture and more shrub-like with lots of basil stems that produce an abundance of flowers.


The origins of the Chiffon series date back to 1986 when Dr. Tachibana at the Osaka Botanic Gardens sent him some seed in response to a correspondence they had concerning the mythical pink Hibiscus. The resulting seedlings were not pink, but contained the doubling genes have gone on to produce Lavender Chiffon, White Chiffon and now three generations later - Blue Chiffon. Woods has now recently returned to single blues to try to incorporate more vigour to the plants and greater flower size.

It has taken Dr. Woods a long time to fully understand flower color and flower form inheritance in Hibiscus. It was considerably more complex than he imagined when he started out.

To date Woods has made over 600 designed and controlled crosses. Some yield much seed on a few attempts, but some, even after 30 or more attempts have failed to set any seed. There are some sterility problems within hibiscus. Remarkably, Woods has flowered over 8300 seedlings yet has only introduced three varieties to the trade! Amongst the un-flowered seedlings in his poly-tunnel he is sure there are another three perfect plants. Plant breeders always think like this and believe their next flower will be the best ever!

While making more crosses and raising more seedlings might produce new flowers more quickly, Woods has found that it is not physically practical for a lone grower to do this. According to Wood’s, “…from what I have learned from recording numerical descriptions of every new flower and analysing the inheritance of dominant, recessive and suppressed characteristics it would not be quicker. Just as many generations would have to be worked through to divide and combine characteristics in desired ways. The important thing however is that the breeder must be obsessed with Hibiscus and prepared to tend them 365 days a year!”

Indeed, Dr. Woods is obsessed, and it all started with that mystery plant he saw in the South of France 27 years ago.
