Nemesia caerulea is a blue- to purple- flowered herbaceous perennial member of the family Scrophulariaceae.[1] The plant is native to the Cape Floristic Province of southwestern South Africa, where it grows at low elevations on fully exposed north-facing and northwest-facing slopes in association with other native grasses and forbs.[2] Its chromosome number is 2n=18.[3]
It produces many small flowers in shades of pink, blue and white (the Latin caerulea means "dark blue").[4] The flowers are two-lipped, the upper lip with four lobes and the lower lip with two lobes. In cultivation the two lips are often different colours.[5]
In temperate regions it is usually grown as an annual. The cultivar 'Sea Mist' has gained the Royal Horticultural Society's Award of Garden Merit.[6]
