Zones 10-11 year-round; grown as annual in zones 3-9

10a 10b 11a 11b

Growth Stages

Seedling

2-3 weeks

Tiny leaves emerge with initial true leaf pair; plant is delicate and compact

Keep soil consistently moist (not waterlogged). Provide bright indirect light indoors. Thin seedlings or transplant to individual containers at 2-3 weeks.

Vegetative Growth

3-4 weeks

Plant develops multiple stems and rounded green foliage; bushy, compact form establishes

Pinch center stems when 4-6 inches tall to encourage branching. Gradually harden off transplants before outdoor planting. Water moderately; avoid waterlogging.

Budding & Early Flowering

2-3 weeks

First flower buds appear at stem tips; initial blooms open, typically pink or white with contrasting centers

Plant outdoors after last frost danger passes and soil warms (60°F+). Space 12 inches apart. Deadhead spent flowers to encourage continuous blooming.

Peak Flowering

8-12 weeks or longer

Plant covered in flowers; continuous blooming throughout summer and fall in warm climates

Water during dry spells (1 inch per week in heat). Apply light balanced fertilizer monthly (moderate nitrogen). Deadhead regularly. Watch for pest and disease issues.

Late Season & Decline

Until frost or indefinitely in zone 10+

In cooler zones, frost damage ends the season; in warm zones, flowering continues year-round with occasional pruning

Prune lightly to maintain shape and stimulate new growth. In zones 10-11, reduce watering slightly in winter if growth slows. Dig up annuals before hard frost.
