Hey, I'm always on the lookout for a disease and pest resistant plant as I think they make the best keepers. Don't know why, but sometimes one plant is kinda like a bug terminator and the rest get attacked by anything going round. I think inbreeding makes them kinda week and susceptible to attack. Making your own crosses and getting hybrid vigor seems to help, and you'll sometimes find that one special one that bugs hate. Anyway, that's my theory.
