This is the plant formerly referenced as a supposed ultramafica hybrid, however appears to simply be a very vigorous spatulata form. Plants grow up to 3" in diameter, with semi-erect rosettes of narrow strap to wedge-shaped leaves. Color can turn solid red in even moderately strong light. Flower stalks are numberous, thin, and sport several small, self-pollinating white blooms. 
Available plants are small but mature, around 1.5" in diameter and may be flowering.
