Growth Stages

1

Seedling/Establishment

3-6 months

Small rosettes of linear gray-green leaves emerge; plant is compact and low-growing

Water regularly but sparingly during first growing season to establish root system. Ensure excellent drainage to prevent root rot. Protect from excessive moisture.

2

Vegetative Growth

6-12 months

Dense mounding habit develops with gray-green needle-like foliage; plant fills out horizontally

Minimal fertilizer needed; avoid nitrogen-rich fertilizers that promote soft growth. Little to no pruning required. Reduce water frequency.

3

Flowering

4-6 months (spring through summer, sometimes into fall)

Tiny pink to white flowers appear in clustered inflorescences (fascicles) held above the foliage; blooms are prolific and long-lasting

Do not deadhead if you want seeds; allow some flowers to mature for wildlife. Light pruning can encourage bushier flowering. Maintain dry conditions.

4

Seed Production & Dormancy

Ongoing after flowering

Flowers mature into small seed heads; foliage may appear less vibrant in winter but plant remains evergreen

Allow seeds to remain on plant for wildlife. Minimal water needed. No special winter care required in appropriate zones.
