|L. vallis-mariae is a group of succulent perennials that is almost stemless and has soft rootstocks that produce inverse, yellowish green to bluish white, cone-shaped pair of leaves that are separated by a fissure. The tops of leaves have light colored speckles or dots. From mid-summer through fall, a single yellow daisy-like flower emerges from the fissure and is as large as the pair of fleshy leaves below. These cold sensitive plants grow best in a cactus potting medium that has been mixed with organic matter such as leaf mold in bright light. Water well from early summer to late autumn and fertilize monthly with a half strength, balanced fertilizer. Soil sure soil is well drained as soft rot may be a problems. Other than that, this plant is really not plagued with many problems.
