At least in the mid-Atlantic states, howabout substituting Euonymous purpera (?sp), the Northern Wahoo, AKA a native burning bush that only burns slightly to the burgundy side, instead of crimson.
It's been rare in cultivation lately, but I know how quickly production- level propagation can turn things around when there's a market & a demand. I've seen rare/threatened/ endangered plants become the things in every garden. For example, in 1996, I had a seasonal job in Environmental Ed restoring tallgrass prairie with several endangered species. One of the state-level endangered was Liatris spicata, aka Gayfeather or common Blazing Star.
Now I only saw the 'wahoo' given as an alternative name for E. alatus! I didn't realize there was a separate plant--a better alternative, it sounds like, too. Thanks so much for pointing this out to me.
What an interesting (but back-breaking) job that must have been. Thank you for your comments!
