flower

Diascia is a charming tender perennial from South Africa, valued for its delicate, snapdragon-like flowers in coral, pink, salmon, and apricot tones. These low-growing, trailing plants reach 6–12 inches tall and spread generously, making them ideal for rock gardens, containers, and hanging baskets. They flower prolifically in cool to moderate temperatures and attract bees and butterflies to the garden.
