Crassulaceae: Houseleeks, Plakkies, Stonecrops

The Crassulaceae is a large family of 1500 species in which most genera exhibit a degree of leaf succulence. Many succulent Crassulaceae are frost-hardy and suitable for use as garden plants and in horticultural displays.
Adromischus are desirable leaf succulents which can be grown on a sunny window ledge. Their varied colour, leaf markings and form makes them highly collectable.
The genus Crassula includes the well-known Jade or Money Plants and other small sub-shrubs, choice minatures and mat-forming plants some of which are frost-hardy.
Cotyledon includes interesting shrubby species with succulent leaves. Some species have showy tubular yellow, orange or red flowers.
Dudleyas and Echeverias are insufficiently hardy to survive a cold, wet winter, but they are often used as summer bedding plants and housed under glass for the winter.
Kalanchoe includes plants with showy flowers propagated through the horticultural trade.
Sedums are well known for hardy mat-forming Stonecrops and for larger hardy species such as Sedum telephium which provides useful flower colour in the garden in late summer and early autumn.
Sempervivum, Jovibarba and Rosularia form clumps of succulent rosettes, with hardy cultivars in many colours and forms. Sempervivums add an exotic touch to any garden.
Tylecodon is a South African genus of small shrubby plants with swollen stems that grow and produce leaves during the winter, flowering in the spring or summer.
