Coleus fredericii, synonym Plectranthus welwitschii, is a species of plant in the family Lamiaceae.

[2] The species was originally described by John Isaac Briquet in 1894, as Neomuellera welwitschii.

[2] It was transferred to the genus Plectranthus by Leslie Codd in 1972.

A 2018 phylogenetic study showed that Plectranthus, as then circumscribed was not monophyletic, and so revived the then defunct genus Coleus.
