Unfortunately I can't say where the cuttings came from because of the trouble I went through to get them and their hesitance to share the material with me in the first place. As my plants grow I will be able to share cuttings and maybe someday plants as well but as you can see in the photos they are still very small rooted cuttings 6-8 inchs tall at the moment. I have heard that wild stands of white blackberries are still around but I've checked every blog, forum, and photo on the web to find someone who grows them with no results. There is a blogger who grows snowbanks white blackberry but hasn't answered any of my emails I've sent him over the years in efforts to acquire some. I first heard of white blackberries about 5 years ago and since then have been looking for them. Another hard to acquire plant is the black fruiting nanking cherry. I have red and I'm rooting white but the black nanking is only available in Cananda to my knowledge and every time I contact the one person online with them I get the same thing no answer. Acquiring rare plants is more difficult than propagating them IMO. well.... All except for Dall'Osso which is very hard to not only root but keep alive. Sorry I couldn't be of more help Margaret but you are more than welcome to cuttings in fall 2017 if you don't mind waiting.
