Orbea variegata (formerly Stapelia v.) is not a bulb. It is, however, easy to grow and bloom in a 4" / 10cm pot. Anybody who likes the coloration of Ferraria flowers will appreciate these, which, unlike its stapeliad relatives, have no aroma whatsoever. It is perhaps best handled in a hanging basket or in the ground as it sprawls. It survives overnight frosts if growing under a shrub but not sustained freezing. Seeds sprout within 2-3 days during warm weather and grow rapidly for a succulent. It doesn't seem to care what kind of soil it occupies. It is susceptible to snails, slugs and mealybugs. I requested some to introduce some genetic variability into my collection. Leo Martin Phoenix Arizona USA
