It amazes me the broad range of experiences with these plants ... I didn't know any carnosa *ever* bloomed. And my multiflora blooms nearly constantly, and has put up with so much abuse, so bizarre that yours croaked, Lin.
Other than the multiflora, my biggest success was lacunosa (not too flashy of flowers, but I loved the scent!). That was in TN, but my friend here in Arizona (who is a terrific plantsman) has never seen his bloom. I'm guessing it's the humidity? We'll see. I got a small one that is literally hanging over the side of my kitchen sink, in order to improve the level of humidity. It's not unusual for Phoenix to run at about 20-30%, or lower.
I also got a "Black Hoya" - Hoya cinnamomifolia var purpureofusca from Almost Eden. Anyone have any experience with this one?
