Wild Flowering Plants
Tradescantia spathacea Swartz, Prodr. 57. 1788.
Syn.: Tradescantia discolor L’Héritier (1788).
Quite rare herb of rocky dry hills in populated areas.
Native to Lesser Antilles, Mesoamerica.
Its distribution in St. Lucia suggests it has escaped from cultivation as an ornamental and is not indigenous.
I believe that this species is a potentially serious invasive of the dry rocky slopes of the Pitons, threatening the native ground flora. It must not be cultivated in that area/removed from it. An awareness programme is required for the community of Fond Gens Libres.
