Diascia 'Rose'

Perennial of the Scrophulariaceae family, this pink-flowered Diascia is of unknown precise identity, probably a cultivar resulting from the abundant horticultural production born from the South African species of the genus, native to the high-altitude meadows and rocky areas of the Drakensberg and the highlands of South Africa and Lesotho.

It forms a low and very branched clump, frankly spreading, 15 to 25 cm in height, with small, cordate, medium green and slightly glossy foliage, very dense. The habit is compact and generous, noticeably more abundant than that of many common cultivars.

The flowers are a delicate pale pink, almost pastel, with a well-developed upper lip marked with a small yellow-orange eye in the center, a distinctive feature visible up close and unique to the genus. They are produced in very large abundance on short stems, forming an almost continuous floral mass that largely conceals the foliage. In cultivation, the flowering extends from May to autumn, with remarkable generosity.

It requires full sun, well-drained and moderately fertile soil. Hardiness remains limited in heavy and wet soil in winter; a well-exposed rock garden or wall suits it better than an ordinary flower bed.
