Growth Stages

1

Seedling

7-10 days

Tiny leaves emerge and form a delicate rosette. Plants are fragile and require high humidity.

Keep soil consistently moist but not soggy. Provide bright indirect light. Thin seedlings to proper spacing once they develop true leaves.

2

Vegetative Growth

2-3 weeks

Plant develops dense foliage and begins forming a compact, spreading mound. Leaves are small and gray-green.

Maintain moderate moisture. Begin hardening off transplants 1 week before planting outdoors. Pinch back early growth to encourage bushier plants.

3

Flowering

8-12 weeks (often longer with deadheading)

Abundant small flowers in warm coral, peach, and orange tones cluster at stem tips. Blooms attract bees and butterflies.

Deadhead spent flowers regularly to promote continuous blooming. Fertilize every 2-3 weeks with balanced formula. Water consistently during hot spells.

4

Peak Bloom

4-8 weeks

Plant is completely covered with flower clusters. Color intensity and fragrance are strongest. Plant may look slightly exhausted in extreme heat.

Deadhead relentlessly for maximum flower production. Provide afternoon shade in zones 8-10 to prevent heat stress. Keep well-watered.

5

Late Season/Decline

Until first hard frost (typically 4-6 weeks in fall)

As temperatures cool in fall, blooming resurges. Plant gradually slows as frost approaches. Flowers remain until first hard frost.

Continue deadheading and watering. Pull plants after first frost; they do not overwinter in most zones. Save self-seeded volunteers if desired.
