Crassulaceae: Stonecrop Family — Crassula & Sedum
The Stonecrop family members are mostly succulents, with basal rosettes of fleshy leaves. Dudleya have numerous flowers, more or less cylindric, ranging from bright yellow to deep orange-red. Other genera, e.g. Sedum (Stonecrop) and certain Crassula have star-shaped flowers. Some plants in this family have an unusual photosynthesis variation, called CAM (Crassulacean Acid Metabolism). These plants conserve water by keeping their pores closed during the day, and opening them at night.
