Diascia (Twinspur): Nonstop Snapdragon-Like Blooms for Containers & Edges

Why Choose Diascia?

From early summer until frost, Diascia (dy-ASS-ee-uh) pumps out clouds of tiny, snapdragon-shaped flowers in rose, coral, pink, and white above delicate, trailing foliage. Perfect for softening the front of a border, weaving through taller perennials, or spilling from containers and window boxes. Hardy in zones 8–10; grown as an annual elsewhere.

Growing Essentials

• Sun: Full sun.
• Soil: Well-drained garden soil or quality potting mix.
• Moisture: Evenly moist—don’t let it dry out completely.
• Grooming: Snip off spent flower stalks to keep the show going.
