As far as I am aware, almost every type of rose can be consumed.
Bamboo is a slightly different matter. There are several different species of bamboo, but in the U.S. you may be more likely to encounter one of two species of cane with some shared properties -- all of which are related to grasses. There are also some invasive species of bamboo taking over some areas.
I have not heard of any species of bamboo or relatives native to North America being poisonous, you may want to be careful of your sources.
