Peter Kukielski knows how to grow roses without chemicals and I have learned a little about disease resistant roses over the past 30 years. One thing I love about our Annual Rose Viewing is the chance to tell visitors that you do not need an arsenal of chemicals to grow healthy, beautiful roses. I did not always know this. My rose education began when we moved to Heath in 1979. In my admiration for Katherine White, wife of the brilliant writer E.B. White, and her book Onward and Upward in the Garden, I determined that I too would grow romantic old-fashioned roses in my country garden from the Roses of Yesterday and Today nursery in California.
The very first rose I planted was Passionate Nymph’s Thigh, sometimes called Cuisse de Nymph, La Seduisante or Maiden’s Blush. This is an old alba rose, a fragrant blush pink rose with slightly blue green foliage and much hardier than you might expect from her name. I came to think that Passionate Nymphs must have a lot of stamina.
The Passionate Nymph is nearly buried right now, but I think she likes the snow and prefers to be blanketed and thus protected from the terrible frigid temperatures of February.
Other hardy alba roses line the Rose Walk, Celestial, Felicite Parmentier, Queen of Denmark, Madame Plantier, and Semi-plena, as well as damasks, rugosas, hardy Griffith Buck roses and nameless farm girl roses. Many of these are fragrant and all have healthy foliage without any help from me. Early hybridizers put fragrance and disease resistance high on their list of vital attributes. What those roses don’t have is a long bloom season. Thus the Annual Rose Viewing is scheduled for the last Sunday in June when, for a brief period, all the roses are in bloom.
Happily for rose lovers, and organic gardeners who never considered growing roses, dozens of new disease resistant roses have been hybridized that also have a long bloom period. It was Peter Kukielski, former Curator of the Peggy Rockefeller Rose Garden at the New YorkBotanical Garden, who first introduced me to the lush First Crush and Cinderella and other hybrids created by the German Kordes company. It was over 20 years ago that the German government outlawed the kinds of poisons that rose growers routinely used. This set the Kordes hybridizers to creating beautiful disease resistant roses with a long bloom season.
Now other hybridizers have hopped on the band wagon. I was a little dubious about roses groups with names like Oso Easy, but these are also roses bred with disease resistance. Drift roses are another family of small shrubby disease resistant rose in shades of peach, pink, coral and red.
Kukielski also introduced me to Earth Kind roses. Again I thought the name was a marketing gimmick, but no, these are old roses tested and classified by Texas A&M to be disease resistant. Red Knock Out, New Dawn and The Fairy are familiar roses that claim the Earth Kind label.
When I spoke to Kukielski recently I asked why the list of Earth Kind roses hadn’t grown any longer. He assured me I shouldn’t have to wait too much longer. In the meantime I can watch the rose trial gardens set up at NaugatuckValleyCommunity College in Connecticut, Cornell University, and at the Deering Oaks Park in Portland, Maine where Kukielski lives and is now leading the northeast rose trials as part of the Earth Kind Team. He is also Executive Director of the American Rose Trials for Sustainability (ARTS) which will soon have a website up and running. He has his own new website the millennial rose garden.
Right now you can get Kukielski’s new book, Roses Without Chemicals: 150 Disease Free Varieties That Will Change the Way You Grow Roses (Timber Press $19.95)
Kukielski wants unhappy or potential rose gardeners to know that failure in the rose garden is not their fault, it is (often) the fault of the rose’s genes. However, he does say that there are things you are responsible for.
Roses need a good site that has at least six hours of sun a day.
Roses need a good soil, with a pH between 5.5-7, enriched with compost and a layer of mulch.
Roses need consistent water especially for the first year or two after planting. However the soil must drain well or the roots will rot.
Roses need annual helpings of compost and an organic fertilizer like Rose-Tone, as well as a renewed layer of mulch.
Gardeners are familiar with hybrid vegetable seeds with disease resistance. New varieties are always being developed to resist various rots, mildews, fusarium and blights. This makes success more sure for the vegetable gardener. Now rose lovers can look for roses with genetic disease resistance and a long bloom period. Red Knock Out Roses have gotten a lot of publicity but some of Kukielski’s favorites are Drift landscape roses in Pink, Peach and Coral, Oso Easy Cherry Pie, Julia Child yellow rose and three Kordes hybrids: KOSMOS (pale creamy peach), Cinderella (pink) and Brothers Grimm (orange). That is just the beginning. More easy care, disease resistant roses are on their way.
I will be giving a talk about the sustainable rose at the Western Mass Master Gardener Spring Symposium on Saturday, March 21 at Frontier Regional High School in South Deerfield. I will also be selling my book The Roses at the End of the Road. For full information about the Symposium go to www.wmmga.org. Hope to see you there.
