Growth Stages

1

Establishment

4-6 weeks

Young plants develop rosette form with fleshy green leaves, establishing root system

Keep soil consistently moist (not waterlogged). Protect from extreme heat and wind. Avoid covering the crown with mulch.

2

Vegetative Growth

Spring through early summer (several months)

Rosettes expand and multiply, leaves thicken and may show reddish tones at tips and edges

Maintain moderate moisture. Remove any dead outer leaves. Ensure good air circulation to prevent fungal issues.

3

Flowering

Late May to July (4-8 weeks)

Tall, slender flower stems (8-12 inches) emerge from rosette centers with terminal panicles of small pink or white flowers with darker pink sepals

Continue regular watering. Deadhead spent flowers to encourage longer bloom. Support tall stems if needed in exposed locations.

4

Post-Flowering & Dormancy

August through winter

Flowers fade and set seed. Foliage remains semi-evergreen; rosettes may show purple-bronze coloring in cold

Allow some flowers to set seed for self-propagation. Cut back dead flower stems. Reduce watering in winter but maintain slight moisture.

5

Rejuvenation

Ongoing throughout growing season

New basal offsets form around parent rosette, creating dense clumps

Divide congested clumps every 3-4 years in spring or early fall. Discard old woody centers and replant vigorous rosettes.
