At the recent show at the L>A> Arboretum I saw caudiciforms that looked like they were grown over rocks. How do they do that? Do they simply pot them up at a young age and wait?
Caudiciforms grown over rocks
Some do it that way; others are constantly searching for just the right rock which will fit into a space that already exists in the plant. The large plants you see at the LA Intercity show have been grown by their owners for many, many years, and they love their caudiciforms there.
