Growth Stages

1

Seedling

3-4 weeks

Small seedlings with soft, sticky foliage and opposite leaves; very delicate stage

Provide bright, indirect light; keep soil lightly moist but not waterlogged; ensure excellent drainage to prevent damping-off disease

2

Vegetative Growth

2-3 months

Young shrub develops branching structure with increasingly sticky, aromatic foliage; no flowers yet

Water regularly but allow soil to dry between waterings; apply light pinching to encourage bushiness; provide full sun exposure

3

Flowering

3-6 months (nearly continuous in mild climates)

Abundant tubular flowers in orange, yellow, red, or bicolor combinations appear at branch tips; flowers attract hummingbirds and bees

Deadhead spent flowers to encourage continuous blooming; reduce watering frequency; provide afternoon shade in extreme heat

4

Mature Shrub

3-10+ years (lifespan)

Established plant reaches full height and width; dense branching with consistent flower production; may lose some foliage in cold winter climates

Prune lightly in late winter to shape and remove dead wood; maintain dry conditions; apply gravel mulch; minimal fertilizer needed

5

Decline

Variable

After 5-10 years, older plants may become woody and sparse with reduced flowering

Prune hard to rejuvenate or propagate from cuttings to start new plants; consider replacement
