USDA Zones: Making Progress
We are proud to announce that we are making headway in the battle to correctly identify in which USDA Zones clematis will grow. The 2004 edition of the American Horticultural Soc
iety A To Z Encyclopedia Of Garden Plants has expanded their zoning for clematis to include USDA Zones 4 through 11.
Numerous garden writers have also acknowledged this expanded zoning in articles they have written. For example:
Aitken, Steve, “Clematis that can take the heat”, Fine Gardening, Jan/Feb 2004.
Ross, Marty, “Clematis”, Country Home Country Gardens, Summer 2003.
Sterman, Nan, “You Say Clematis & I Say…”, San Diego Home/Garden, May 2003.
Riccio, Peggy, “Clematis: Queen of Climbers”, ChesapeakeHome, April 2003.
Cohoon, Sharon, “Clematis In Mild Climates?”, Sunset Magazine, April 2002.
Malek, Edith, “Clematis for American Gardens.”, The American Gardener Magazine March/April 2002.
Sawyer-Fay, Rebecca, “Clematis”, Country Living Gardener, August 2000.
The society would like to recognize growers and mail-order nurseries that have accepted USDA Zone 4 through 11 criteria for clematis. As it stands now, the one brave soul out there to attribute the correct zones to his product is Dan Long of Brushwood Nursery. As more nurseries come around to our way of thinking, we will list them on the website.
And finally, the book by Edith Malek, Simply Clematis…Clematis Made Simple gives clematis gardeners a concise yet comprehensive guide about growing clematis, that includes a section on addressing correct zoning.
