Not a generally well-known name among gardeners, Plectranthus
is a genus of plants in the mint family, Lamiaceae.
Closely related to Solenostemon (coleus),
most species are grown for their foliage, attractively variegated
in some cultivars, rather than their flowers. All require
protection from frost, and several make good houseplants.
