Additional comments: Bunny ears cactus is an excellent small-scale prostrate and spreading plant for use in desert gardens as a ground cover. O. microdasys var. albasplina has white glochids, O. microdasys subspecies rufida has glochids that are more rusty brown colored. And here's a bunny ears called Opuntia microdasys var. pallida forma cristata with yellow glochids and fastigiated stem pads...very cool!!!
