Excellent member of the Crassulaceae which means it is a succulent basically, but one that eschews the arid sunny spot in favor of lusher environs like our shade garden with dairy manure mulch. Makes a thick clump of fleshy green leaves with taller stems of pendulous strings of bead-like yellow flowers that are nothing less than captivating. This is one of those plants we have had for a long time but one that surprises us each year when it blooms because we don't expect something so familiar to float our boat quite so high. Very easy to please and a plant people want when they see it in flower.
