Planting & Care

Start seeds indoors in late winter or early spring. Sow in seed-starting mix, press seeds gently into the surface, and cover lightly with vermiculite or fine soil. Keep consistently moist but not waterlogged. Germination typically occurs in 14-21 days. Once seedlings have two sets of true leaves, transplant into individual pots and grow on in a bright, cool location. Harden off before planting outdoors after the last frost date.

Choose a sunny spot with well-drained soil. Water regularly during the growing season, but avoid overhead watering to prevent disease. Mulch around plants to retain moisture and suppress weeds. Deadhead spent blooms to encourage continued flowering. In zones below 7, dig up tubers in fall and store in a cool, dry place for winter.
