Clivia is a member of the Amaryllidaceae family. Clivia, however, does not form bulbs. Instead the plants have large, fleshy, white-and-yellow roots. Their deep-green leaves are two-ranked—arising from the soil directly opposite one another in an alternating sequence. Because the leaves arch directly above one another, a mature plant develops a symmetrical, fan-shaped silhouette that provides a perfect setting for its masses of trumpet-shaped flowers.
Native to damp woodlands in southern Africa, the habitat ranges from subtropical coastal forests to ravines in high-altitude forests, where they thrive in dappled shade and in well-drained, humus-rich soil. In their native habitat, the plants are often found in large colonies. Unfortunately, many colonies of Clivia have been destroyed by harvesting for traditional medicine; the plants are extremely toxic to people and pets but are used medicinally for various purposes.

The cultivar 'Sir John Thouron' is valued for its showy, pale yellow flowers that form a ball-shaped umbrella above its dark-green leaves. The flowers are smaller versions of amaryllis blossoms, clustered atop a thick, fleshy stalk. This cultivar was developed over many years at Longwood Gardens https://longwoodgardens.org/gardens/research-and-conservation/selected-r....
