M. matudae is a fast growing cactus that topples under its own weight, then continues to sprawl along the ground in a snake-like fashion. It will grow over or around anything in its path. The two arms of my M. matudae are 10 and 12 inches now, and already leaning. It will continue to lean and eventually become too unwieldy for a pot.
After the flowers are spent, M. matudae produces greenish fruits that eventually dry and fall off. The attractiveness of the flowers and fruit makes this rather nondescript cactus interesting through fall.
