I have seen many a cross of seeds by Liz for sale using their Fruit Salad Brugmansia. The only reason I didn't try those is that I believe Fruit Salad is a smaller bloom. (I really do prefer the larger blooms over smaller ones, the impact is so much more apparent and dramatic when in a bloom flush!)
(sigh....) I've had a few others tell me there is no way to tell which plant is which cross by sight ... I sure wished my cat hadn't messed up my tags. I'd sure like to know because then I can back-trace the genetics to see where some of the seedling's characteristics might have come from. The red bark has me VERY curious. Has anyone here seen red bark on any brug cultivars or species before?
