Growing Purple Gem

Plant your tubers in full sun after your last frost date in well-drained soil. Pinch the main shoot when it reaches four sets of leaves to encourage branching and more blooms. Stake early since the tall stems can get top-heavy as flowers open. Deadhead regularly to keep the flowers coming right up until frost.

Spacing
Space roughly 2–3 ft apart
Staking
Staking recommended once buds set
