Ahhhh, what? I missed something here. Anyway, my D.capensis
all green do come true from root cuttings. Why wouldn't they?
I also expect it to come true via seed. It's not a sport or
some such. It is a mutant in which the plant produces no reddish
coloring. Most species have such mutants and those that don't,
well it's only a matter of time before somebody finds them.
