Growth Stages

1

Seedling/Establishment

4-8 weeks

Tiny grass blades emerge, very delicate and sparse appearance

Keep soil lightly moist but never waterlogged; provide bright light; protect from wind and heat stress

2

Vegetative Growth

6-18 months

Plant develops dense clumps of fine, hair-like green foliage; gradually increasing in size and bushiness

Water moderately during first growing season; reduce frequency as plant matures; establish deep root system; minimal fertilization needed

3

Mature Clump Formation

Ongoing, 1-2 years to reach full maturity

Plant reaches 2-3 feet in height and width; forms a dense mound of fine-textured foliage

Transition to drought watering; may apply light slow-release fertilizer in spring; monitor for overcrowding

4

Flowering

6-10 weeks

Delicate, feathery panicles emerge in late summer to fall (August-October), ranging from tan to reddish-purple tones

Do not deadhead if you want seeds; drought stress often triggers better flowering; minimal intervention needed

5

Senescence/Dormancy

November-February

Foliage turns golden-bronze to tan in winter; dried seed heads persist and provide visual interest

Do not cut back until late winter or early spring (February-March); dry foliage provides winter shelter for wildlife; hold off watering
