Growth Stages

Establishment

4-6 weeks

Water consistently (not saturated) for first 4-6 weeks. Mulch lightly around base. Avoid fertilizing; native soil is adequate.

Active Growth

3-5 years

Rapid lateral expansion; foliage develops fuller color and texture

Water during dry spells. Light pruning to shape can begin in spring. No fertilizer needed.

Maturation

2-3 years

Plant reaches full compact mounding form; foliage becomes denser and develops deeper blue-green to gray coloring

Minimal watering except during drought. Light pruning to maintain shape. No fertilizing required.

Mature/Maintenance

Indefinite (long-lived)
