Crassula is Latin for a small fat female entity. The specific name congesta refers to the very densely congested head of flowers forming the inflorescence Crassula congesta subsp. laticephala is one of two subspecies found between Barrydale and Oudtshoorn. They are monocarpic and rare. These plants make excellent little pot subjects with their showy downward curling leaves and sweetly scented flowers which is possibly pollinated by moths. They generally only live for at the most 3 years and die after flowering. The flowers can be cut off before opening to prolong their life or you could try your hand at planting the seed. They are very drought-adapted members of the genus and are usually found growing in full sun in open gravel plains usually associated with white quartzite pebbles.
