The American Bamboo Society website has information about the amount of sun/shade for each type of plant. However, after reading through many threads, I have noticed a great amount of confusion in this area. We are in the southern gulf islands here, which gets a fair amount of summer sun, and precious little in winter. To the immediate south of the Japanese garden where my bamboos will all be going, the neighbours have a variety of trees, mostly firs and cedars many of which exceed 100' in height. Unless they catch the dreaded Husqvarna disease, I fear I may never see any winter sun on the garden. Do I try to put the plants in the sunniest part of the garden, or will it really make that much difference. I'm not expecting to grow 40' tall bamboo here!
