I searched a long long time before I found any, dogwood's natural state is that the tree will not get very big, and the wood itself is often curled and twisted, making it hard to find good straight grained wood for boxes, but once you find some that can be cut into 4" squares for pots or scratch boxes you had best grab it, green or not! I got mine from a local tree service outfit, they cut the trees and had a pile of them I went and cut the wood myself, (son inlaw) stored it till it was dry enough to use.
