Bigenerics and variegation
I recently posted some pictures of a variegated Foxtail Palm (Wodyetia bifurcata) seedling on another forum, and speculated as to the cause of the variegation. The consensus of the respondants seems to be that what I have is most likely a hybrid between Wodyetia and some species of Veitchia, as they are apparently known to cross and produce variegated offspring.
My question is: why would bigeneric hybrids be more prone to variegate? Is this a known phenomenon in any other plant families? I have made several bigeneric bromeliad hybrids with mixed success, but never had any come out variegated. This is the first I've heard of this happening.
