Growth Stages

1

Seedling

3-4 weeks

Tiny seedlings with first true leaves emerge; very delicate and slow-growing initially

Provide bottom heat (70-75°F), high humidity, bright indirect light. Keep soil evenly moist. Thin seedlings to prevent damping off.

2

Vegetative

4-6 weeks

Plant develops bushy growth with increasing leaf production; compact, mounding form establishes

Pinch back growing tips early to encourage bushiness. Provide bright light and consistent moisture. Begin light fertilizing.

3

Flowering

8+ weeks (extends through season)

Small tubular red flowers with yellow tips appear throughout the plant; blooming is prolific and continuous in ideal conditions

Deadhead spent flowers regularly to promote continuous blooming. Provide full sun and warm temperatures. Feed with balanced or slightly higher phosphorus fertilizer every 2-3 weeks.

4

Mature/Established

Ongoing

Plant reaches full size (6-12 inches tall and wide depending on variety); maintains dense, compact form with continuous flower production

Maintain consistent watering and feeding schedule. Monitor for spider mites in dry conditions. Provide some shade in very hot climates. Can be brought indoors before frost.

Harvest Tips

Elf is grown for ornamental flowers rather than harvest. Deadhead spent blooms by pinching off flower stems just below the flower to encourage more blooms and maintain compact shape. Cut back lightly after heavy flowering periods to rejuvenate.

Fun Facts
