native american bittersweet is an endangered species. it has been largely replaced with chinese bittersweet which is much more agressive. both are common here in Northeast.

I think both are beautiful, and always cut some (chinese only!) in the fall for a fall bouquet. (turning foliage, (ie, crimson, or golden) stays fresh for weeks if you add glycerin to the water-- 1 part glycerin to 3 parts water. most drug/chemist stores sell glycerin. an 8oz. bottle cost under $1 usually.. it also works very well for holly and ivy (if you like those greens for up coming holiday.. )

i think for a tree, you'd need a gallon!--
