Growth Stages

1

Establishment

4-6 weeks

Young plant develops initial root system and begins establishing its rosette pattern

Keep soil lightly moist but not wet; provide bright indirect light; maintain warm temperatures (65-75°F); avoid fertilizing until established

2

Vegetative Growth

Several months to years

Rosette gradually expands with new leaves emerging from the center; plant maintains compact form

Water only when soil is completely dry; provide excellent drainage; rotate pot monthly for even growth; maintain 50-75°F in cooler months

3

Maturation

Ongoing

Plant reaches mature size; rosette fully formed and may begin offsetting (producing baby plants)

Continue sparse watering; ensure bright light conditions; maintain temperatures above 50°F; allow offsets to develop before separating

4

Flowering

3-6 weeks

Tall inflorescence emerges from the rosette, producing small tubular flowers in pink or coral-red shades arranged along the spike

Maintain regular watering schedule during blooming; provide bright light to encourage flower production; flowering typically occurs in spring

5

Dormancy

3-4 months

Plant enters a resting phase during fall/winter with minimal growth and no flowering

Reduce watering to monthly or less; decrease fertilizing completely; maintain cooler temperatures (50-60°F) to promote next season's flowering
