Weird Worm
Per Richard O.: "This is from my friend João Vianna in Brazil, whom I imported it from. It is a strange one with weird monstrose and variegated growth. The "weird" part is fickle and can be prone to fungal issues so hit it with Mancozeb! Weird Worm likes to be isolated for it's unusual looks so have grafting stock ready."
