Gaura produces airy clouds of small butterfly-like flowers on wiry stems over a very long season. Genuinely tough once established, tolerating poor soil and drought, and adding movement to the garden. Full sun. Well-drained soil. Drought tolerant. Cut back hard in late winter to encourage fresh new growth. Sparkle White produces masses of pure white flowers on fine, arching stems - the lightest and most airy of the Gaura selections.
