Growth Stages

1

Seedling

2-3 weeks

Tiny plants with first true leaves emerge 7-10 days after sowing. Seedlings are delicate with pale green foliage.

Keep soil consistently moist but not waterlogged. Provide bright indirect light. Thin seedlings or transplant to individual containers when 1-2 inches tall.

2

Vegetative Growth

3-4 weeks

Plants develop multiple stems and increasingly bushy foliage. Leaves are lance-shaped and medium green; plant reaches 4-6 inches tall.

Pinch back growing tips once plants reach 3-4 inches to encourage branching and compact form. Ensure consistent moisture and bright light. Harden off transplants before planting outdoors.

3

Flowering Initiation

2-3 weeks

Flower buds form at branch tips. Plant continues to expand and may reach 8-12 inches tall.

Begin fertilizing weekly with balanced or slightly lower-nitrogen formula to encourage blooms over foliage. Maintain consistent watering and full sun exposure.

4

Heavy Flowering

6-10 weeks (extends until frost)

Abundant bi-colored coral-orange and cream flowers bloom continuously. Plant reaches full mature size of 12-18 inches tall and equally wide.

Deadhead spent flowers weekly to promote continuous blooming. Water at soil level to prevent fungal issues. Apply balanced fertilizer every 2-3 weeks. Monitor for pests.

5

Late Season & Decline

Until first frost

Flowering continues but may decrease as temperatures cool. Growth slows significantly as frost approaches.

Continue deadheading to extend bloom. Reduce fertilizer applications. Plant will stop blooming after first hard frost (28°F or below).
