The more color the better – Red Majestic Corylus



The more color the better.

Harry Lauder’s Walking Stick, or the Contorted Filbert or Hazelnut, (Corylus avellana 'Contorta') has never been hard to find in better garden centers, but is it by no means a common landscape shrub. Prized for its corkscrew-like stems it’s at its best in the winter and in early spring before the leaves emerge to hide its interesting stems. During the rest of the year it is a plant that simply fades into the background, unnoticed until the next winter.

Harry Lauder’s Walking Stick had had an extreme makeover with the introduction of Corylus ‘Red Majestic’ (patent #16,048). This gem is great addition to the garden pallet because it has red-burgundy foliage in addition to its interesting curly stems. ‘Red Majestic’ is at its best in the spring as the new, bright red foliage emerges and begins to grow. As summer approaches and as the temperatures rise, the foliage turns to a dark burgundy and then by mid-summer the mature foliage turns to a dark green. Even when the older leaves turn green, all is not lost; the new growth continues to push out red foliage to contrast with the old.

The more color the better, that’s what I say. If a plant is to get from the nursery into the garden it has to have more color, more seasons and more ornamental interest than four to six weeks of duration. I don’t know about you but I no longer have room for shrubs that offer just one season of interest. That being said, I have made room in my garden for ‘Red Majestic.’

Red Majestic was developed in Germany by Rolf de Vries. Garden centers can purchase the plants from these officially licensed wholesale growers: Bountiful Farms Nursery, Broken Arrow Nursery, Canadale Nursery, Ekstrom Nursery, Handy Nursery Company, Hollandia Gardens, Means Nursery, Monrovia Growers, Pierce & Son Nursery, Willoway Nurseries.

Retail purchases can be made at on line Wayside Gardens.

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.

Create the Perfect Hydrangea



It’s that time of the year when I go through all my notes and photographs and complete my evaluations on all the new plants we’re testing. Right now, I’m reviewing all of our potential Hydrangea macrophylla introductions.

Evaluating and introducing Hydrangeas is a long process. For example we work with several Hydrangea breeders in Europe that are doing some really cool work. The picture above shows my travel buddy Dale Deppe, the owner of Spring Meadow Nursery, in a breeder's greenhouse surrounded by unnamed Hydrangea varieties. Our job that day was to determine which plants were good and worth pursuing. It wasn’t easy, but we made our initial selections. Later that year cuttings were shipped to us in Michigan. There's a two year quarantine on Hydrangea (a well as many other species) so during this time we test, evaluate and try to determine if the plants will work for our customers and the American gardening public.

I’ve invested years combing the globe for some really cool Hydrangeas. I’ve also committed years to my own hydrangea breeding program. In all, I have assembled a wide range of excellent plants with a wide array of attributes.


We have plants that rebloom and those that don’t rebloom. We have plants with mop-head flowers and lace-cap flowers. We have miniature plants, plants with bi-colored (variegated)flowers, ground covering plants, plants with dark black stems, and plants with massive flowers. You name it we have it. But what should we introduce? That is the question.

I need your help. Take a short survey and tell me what you think about Hydrangeas. Your answers will help me decide which, if any, of my Hydrangeas will hit the market.

Since the 1940s Fernwood's founder, Kay Boydston, and subsequent garden staff have searched near and far for hardy ferns and many other interesting plants for Fernwood's collections. Steven Bornell, manager of Fernwood's plant collections, along with Ann Desenberg, Fernwood's plant recorder, share their "picture album" along with some interesting facts and anecdotes behind some of the noteworthy plants on the property.
Weather permitting, an optional short walk at the end of the program is offered to see some of the plants discussed earlier.

Shrubs with Unique Architecture



Some years back, I received a call from Gary Koller, a well-respected garden designer in the Boston area. Gary urged me to find and offer more shrubs with narrow, columnar growth habits. In his opinion, we needed plants with a smaller footprint that took up less space in the landscape. He also felt these shrubs added interesting architecture to gardens. The trend toward smaller home lots dictates the need for smaller and/or narrower shrubs. After all, who has the space for a Spiraea x ‘Vanhouttei’ in their garden anymore?

Narrower shrubs have another great benefit; they require less care and maintenance. Growers spend less time spacing and pruning them which saves them money. Homeowners also benefit from these shrubs as they save them both time and effort. Berberis t. ‘Helmond Pillar’, Sunjoy™ Gold Pillar (Berberis t. ‘Maria’), Buxus sempervirens ‘Graham Blandy’, Sky Pointer™ (Ilex crenata ‘Farrowone’), Castle Wall™ (Ilex x meserveae ‘Hechenstar’) and Fine Line® (Rhamnus frangula ‘Ron Williams’) are a few narrow plants that have seen increased popularity over the last few years. I suspect this trend will continue.

ANLA New Plant Pavilion


I just got back from the ANLA Management Clinic in Louisville. Each year at the clinic, NMpro Magazine hosts their New Plant Pavilion where growers and breeders showcase their newest offerings. This year the pavilion featured 42 new plants. That's right - 42 new plants! There seems to be no shortage of new varieties.

While at the conference I heard someone say that we have way too many new plants. In some respects I agree - there are too many new plants. The problem is that there is no way that people, let alone nursery professionals, can digest so many new introductions, let alone grow them.

I see the same thing when I travel overseas. New plants are a dime-a-dozen. As I've said before the difficulty is not finding new plants, it's finding new plants that are better and superior, and that people will want to put in their yard.

To make matters worse, in one of the clinic lectures, one retail expert said that garden centers need to cut back on the number of plant varieties they offer. His point was that by offering so many choices, we are overwhelming the consumer. Again, In some respects I agree. Unless a garden center has a customer base of avid gardeners and plant collectors, too many plants can make it overwhelming for casual shoppers.

So what’s the Answer? In my opinion the free market will solve the problem. The best plants will rise to the top as growers, retailers and consumers vote with their pocket books. With this in mind, it’s very important for growers to be careful in introducing new plants or they’ll soon discover that they’ve wasted a lot of time and money.

To help me avoid making these kinds of costly mistakes, I’ve developed a check list that reflects the plants attributes I feel are needed to be successful. Here’s my simplified check list that I use when considering a new plant:

More Color. The trend in gardening or more correctly - yard decorating is color. Plants with a longer bloom season, multiples seasons of color (flowers, fruit, fall color), colorful foliage that lasts beyond the flowers, etc. are all high on my list.

Easy to grow. The majority of people do not know much about gardening. They want to plant it and enjoy it, so I look for shrubs that are dwarf or compact that requires little or no pruning. I look for plants (particularly roses) that do not have to be sprayed. And I look for plants that do not require special fuss.

Lastly, I look for plants that connect with our emotions. In other words, plants that make us feel good. Everyone likes to feel good. Who can resist the sweet fragrance of a Lilac or the joy evoked by a flock of brightly colored butterflies darting about a Butterfly Bush? Not me, and I suspect most people feel the say way. Certainly a rose connects with our emotions, but the need to spray it can negate those feelings - so even plants that connect with out emotions must be easy to grow.

The days of breeding plants strictly for bigger flowers are long gone. Sure big flowers are great. A Dahlia has a remarkable flower, but only the rare enthusiast is willing to overlook its ugly habit and excessive need for care. Times have changed, and so must the nursery industry.

Is Sumac Garden Worthy?



Rhus (Sumac) gets little attention from gardeners, but the species does offer some real gems that are especially well-suited for the landscape. While most of the species in the genera are not showy enough to suit the typical gardener, many of the plants have outstanding attributes such as showy fall color, drought tolernace, showy fruit and the ability to thrive with neglect .

The fragrant sumac, Rhus aromatica, is the most commonly grown species. The cultivar ‘Gro-Lo’ is a favorite of landscape architects. It is a hardy (zone 3-8), low growing plant (24”), with glossy leaves and superb orange to red fall color. Its dense, suckering habit make it an excellent ground cover especially for slopes and other difficult sites.

Rhus typhina, the Staghorn sumac, is perhaps the best ornamental shrub of the group. The plant has fuzzy stems (like a stag’s horn), great orange to deep red fall color and attractive red seed heads. I learned this plant as a young boy when my dad tought me how to make staghorn lemonade with its fruit. It’s a native shrub that is commonly found along highways forming dense clumps. At 70 mph, it's easy to see that each clump differs genetically in size, fall color, and fruit. Unfortunately, as it is a suckering plant, most gardeners don’t have the room for a clump in their garden. There are several excellent cultivars that are garden worthy; ‘Disecta’ aka ‘Laciniata’ is grown for its attractive lacy cut leaves. Tiger Eyes or ‘Bailtiger’, is a yellow leafed selection of ‘Disecta’. This plant has all the wonderful attributes of the species but with bright yellow leaves that gives summer-long interest.


Staghorn Sumac

Rhus copallina is commonly known as Flameleaf or Shining Sumac. This native shrub can reach upwards of twenty feet in height. The cultivar Prairie Flame aka ‘Morton’ is a compact selection that remains under seven feet tall. It has exceptionally brilliant, red fall color. Over the last few years I have been selecting plants that are as short as 12 inches tall. I think these may have great landscape potential. I have also heard of a cultivar with dark purple leaves called ‘Lanham’s Purple.’ While I have never seen this plant, I think it may have garden potential.


Shining Sumac

Rhus chinensis (pictured above) is a sight to see both in flower and in fall color. It is one of the larger species, forming a small tree up to 24’ in height. Like all the other Rhus mentioned here, this is a suckering plant so use good judgment when choosing a place to spot Rhus chinensis. This species has perhaps the showiest of flowers. It has large, 6-10” creamy-white panicles in late summer, that mature into orange red fruit.

As Rhus are suckering plants that are propagated by root cuttings, they will never be commonly grown. This does not mean they are not worth growing. I saw wonderful mixed shrub planting at a hotel in Portland, Oregon that was simply spectacular. I was instantly impressed with the creativity of the designer because he/she incorporated Rhus typhina into the design and pulled it off. All of these Rhus species have a lot to offer in terms of drought tolerance, fall color, fruit and fall color that can be utilized by creative designers. So yes, in my opinion Rhus is garden worthy.
