As a follow up to my last posting, I have assessed all the climbers and ramblers that were well established in my garden prior to the past winter. Roses that were planted at the end of the summer or fall were not included.
These roses had NO dieback at all: Aenchen Von Tharau, Alchymist, Alexander McKenzie, American Pillar, Asta Von Parpart, Aurelia Liffa, Awakening, Bleu Magenta, Blushing Lucy, Brite Eyes, Captain Samuel Holland, Corporal Johann Nagy, De La Grifferaie, Dr. Hurta, Dorothy Perkins, Dusterlohe, Erinnerung an Brod, Evangeline, Excelsa, Forstmeister’s Heim, Futtaker Schlingrose, Gerbe Rose, Geschwind’s Nordlandrose, Geschwind’s Orden, Geschwind’s Schonste, Goldbusch, Himmelsauge, Isabella Skinner, Jasmina, John Cabot, John Davis, Josephine Ritter, Laure Davoust, Leverkusen, Lillian Gibson, Long John Silver, Maigold, Manita, Marie Dermar, Marie Victorin, Minnehaha, Nymphe Egeria, Ovid, Polstjarnen, Prinz Hirzeprinzchen, Quadra, Ramblin Red, Rosarium Uetersen, Russelliana, Scharlachglut, Summer Wine, Super Dorothy, Theano, Thor, Veilchenblau, Venusta Pendula, White Dorothy, White Mountains, William Baffin, William Booth, Winner’s Circle, Wodan

These roses are crown hardy: Aloha, Antike 89, Autumn Sunset, Salita, Westerland
So, what generalizations have I come to this spring?
Note: There might be some variation in comparing your experience with mine, as hardiness is also affected by micro-climates or the positioning of a rose within your garden. Please comment on your experience with these roses after this past winter. Include your location and growing zone. I’ve got to get back to mowing before it rains again.
The first rose book I ever read was Peter Malins' Rose Book. It was relatively new then and was one of the few books available that had information on old roses. It was the source of my first wish list of roses I wanted to grow. I was lucky enough to pick up the exact copy that I had read back in the early 80s at the Friends of the Library Book Sale. It had been discarded by the Tompkins Public Library. While there are many books that are better, this one holds a special place in my heart.
I have countless encyclopedias of roses. The one I refer to most often is Botanica’s Roses. It covers over 4,000 varieties and provides good information on each. The next one I look at is The American Rose Society Encyclopedia of Roses by Charles and Brigid Quest-Ritson . While it covers only about half the cultivars as does Botanica’s Roses, it does so with a critical eye.
Sometimes, I need more in depth information than either of these encyclopedias provide. When I need information on climbers and ramblers, I immediately grab Climbing Roses of the World, by Charles Quest-Ritson. It is encyclopedic in nature, covering about 1,600 climbers and ramblers. Quest-Ritson applies his critical eye here as well.
While not covering as many varieties, Stephen Scanniello’s Climbing Roses is invaluable in that it is arranged chronologically, has a more in depth look at some climbers and ramblers, and includes his own experience growing these roses in the Cranford Rose Garden at the Brooklyn Botanic Garden.
I also refer to G.A. Stevens’ Climbing Roses. It provides a period look at the climbers and ramblers available up to that time (1933). It has good information about specific varieties that are often forgotten today and great photos.
Once I have decided what rose I “need” to have next in my garden, I turn to Peter Schneider’s Combined Rose List to find sources for that rose. This book is updated annually. For more information see www.combinedroselist.com
As for magazines, my favorite is Rosa Mundi, the Journal of the Heritage Rose Foundation. It comes out twice a year. Each issue is like a small book, loaded with information and photos not often found anywhere else. I look forward to every issue and refer to past issues regularly. Luckily, the Rose Hybridizers Association Newsletter comes out quarterly. It is a little known gem. When I retire from teaching and have more time, I hope to try my hand at hybridizing roses- cold hardy, disease resistant, fragrant climbers and ramblers. Reading this Newsletter is preparing me for that time and whetting my appetite.
In a future blog, I will talk about some other categories of rose books I treasure.
