Selaginella kraussiana, Krauss' spikemoss, Krauss's clubmoss, or African clubmoss, is a species of vascular plant found naturally in the Azores and parts of mainland Africa. It belongs to the very ancient lineage of plants known as the clubmosses.
Its native distribution is the Azores, the Canary Islands and parts of south and east Africa. Since its introduction to Britain in 1878 it has spread slowly, and was first recorded in the wild in 1917 in west Cornwall (UK) and County Leitrim (Ireland), often as a greenhouse weed.
Selaginella kraussiana is cultivated for ornamental purposes. It requires a minimum temperature of 5 °C (41 °F), and in temperate regions is grown under glass as a houseplant. The species and the cultivar ‘Brownii’ have both gained the Royal Horticultural Society's Award of Garden Merit. Other cultivars include ‘Aurea’ and ‘Gold Tips’. They prefer a sheltered spot in full or partial shade, in moist, well-drained acid or neutral soil.
In the Winter a cultivar often described as Selaginella kraussiana 'Frosty Fern' is sold as a house plant due to its white tipped foliage, however this is more normally the taller growing Selaginella martensii rather than the shorter, creeping krasussiana.
