As some of you probably know Cyphostemma is a genus of plants with a large above-ground succulent caudex. Below ground they have tubers. Recently, a friend dug up a speciimen of C. 'Fat Bastard' and found that side-tubers had formed. The growths were roughly spherical, each with a diameter of up to 5 inches (12.5 cm). One of the parents is said to be C. hardyi. When it was dug up the side tubers were even larger. Truly impressive. Does anyone here know whether these side tubers will grow and produce above-ground growth when separated from the original plant? Andrew San Diego
