Lampranthus spectabilis, the trailing iceplant (a name it shares with other members of its family), is a species of flowering plant in the family Aizoaceae, native to the Cape Provinces of South Africa. The unimproved species and a number of cultivars are commercially available, including 'Tresco Apricot', 'Tresco Brilliant', 'Tresco Fire', 'Tresco Orange', 'Tresco Peach', 'Tresco Pearl', 'Tresco Purple', and 'Tresco Red'.
L. spectabilis contains mesembrenol and low levels of related alkaloids such as mesembrenone and have sometimes been mismarketed as Kanna (Sceletium tortuosum) extract which contains higher levels of related alkaloids.
