Growth Stages

1

Establishment

2-4 weeks

Young plants or freshly rooted cuttings develop root systems

Keep soil lightly moist (not wet) for 2-3 weeks until rooted; protect from direct sun initially; provide warm temperatures

2

Vegetative Growth

Several months to 1-2 years

Compact mats expand slowly with dense, clustered leaves; plants mature in shape and size

Water minimally during growing season (spring/summer); provide excellent drainage; fertilize lightly with low-nitrogen fertilizer monthly if desired

3

Flowering

Spring to early summer (3-4 months)

Small pink to magenta daisy-like flowers emerge from leaf axils; flowers open in daylight hours

Maintain consistent temperature and light; reduce water slightly; flowers last 1-2 weeks per bloom cycle

4

Dormancy/Rest

Fall and winter (4-6 months)

Growth slows significantly; plant consolidates energy reserves

Minimal watering (once monthly or less); cool temperatures (50-60°F) ideal; reduce fertilizer
