Full nameTradescantia spathacea ‘Concolor’.
Name statusAccepted, the valid name for a unique cultivar.

Established by Baker (1868). Because it was published before 1959, the Latin name can be accepted (Brickell et al., Art. 21.11).
ClassificationIt was originally published as a botanical variety, Tradescantia discolor var. concolor (Baker, 1868), then reclassified as a botanical form, Rhoeo spathacea forma concolor (Stehlé, 1970). Both are now considered synonyms for the species Tradescantia spathacea (POWO, 2022), so the plant is instead treated as a cultivar with the same name (Brickell et al., 2016, Art. 2.4).
Legal protectionNone.
AvailabilityLocally available in some locations, although not widespread in cultivation.


Described with reference to the RHS Colour Chart (6th Edition; 2019 reprint).
