Growth Stages

Establishment

6-12 months

Young transplant establishing root system; blue-green foliage is developing but not yet dense

Water regularly during first growing season to encourage deep root development. Avoid fertilizing; mulch with 2 inches of coarse gravel. Protect from strong winds.

Vegetative Growth

1-2 years

Plant develops denser branching and more compact mounding form; foliage becomes fuller and more vibrant blue-green

Minimal pruning needed; light pruning only to maintain shape. Continue low-frequency watering during dry periods. No fertilizer required on average soil.

Maturation

Ongoing, 3+ years

Reaches full mature size of 2-3 feet tall and 3-4 feet wide; dense, finely textured foliage with consistent color

Maintain shape with minimal pruning in spring if needed. Ensure good drainage around plant. Little watering needed except during extended drought.

Dormancy

3-4 months

Winter rest period; foliage may show slightly purplish or bronze tints in cold weather; growth slows dramatically

No watering unless soil is completely dry. Avoid pruning in fall; prune in spring only. Protect from harsh winter winds with burlap in colder zones or exposed locations.
