distribution_en:

description_en: Genus of about 50 species of annuals and semi-evergreen, occasionally ever-green, sometimes suckering perennials found mainly in mountains in southern Africa. Erect, semi-erect or prostrate stems bear opposite, ovate or heart-shaped to elliptic or linear, toothed, mainly mid-green leaves. Diascias are valued for their long flowering season; they produce terminal racemes of tubular, 5-lobed flowers, the lower lobes broad, the paired upper lobes having 2 backward-pointing spurs and a translucent yellow "window" at each base. Grow at the front of a border, on a sunny bank, or in a rock garden.

hardiness_en: Most are hardy to -8°C (18°F).
