Weldenia is a monotypic genus of flowering plants in the family Commelinaceae, first formally described in 1829. It has one single species: Weldenia candida,[1] which grows natively in Mexico and Guatemala.[2] [3]
This herbaceous perennial has broad green, strap-shaped leaves growing in a rosette. The central, three-petalled, bright white flowers are borne over a long period in late spring and summer. Hardy down to -5C, in temperate zones it prefers mild sheltered locations in full sun, with neutral or acid well-drained soil.[4] It requires dry conditions over winter, so is best grown in an alpine house or similar, where protection can be provided.
The Latin specific epithet candida means "shining white".[5]
