Hi Jay,
Yeah manzanita is great. The "little apples" are great tasting little balls of what tastes like a hydrated cider mix or something. And as far as rot resistance, I just dug out some 3 year old manzanita from a hugel because it just won't go soft! It's like it is rising to the surface and making it hard to plant in there.
Oh and Arbutus is my favorite tree! They are wierdly similar, they are both red, burn crazy hot and shed their skins like a snake. OK Sorry for the hijack everybody!
