I've only had luck with one - a NOID with white edges on the leaves. All of the frosty ones don't like my garden. Maybe there's something to the moisture thing because my shady spots can be dry even though I supplement water in the summer (and it seems like it's never enough). On the other hand, the species B. macrophylla is totally out of control in wilder areas. It's a toughie to control and edit out.
