Growth Stages

1

Establishment

First 1-2 years

Young plant with soft, juvenile feathery foliage; growth is slow and compact

Water consistently to keep soil moist. Avoid heavy pruning. Apply 2-3 inches of mulch around base, keeping it 3-4 inches from trunk.

2

Vegetative Growth

Years 2-5

Plant develops fuller form with denser branching; blue-gray coloration intensifies

Water during dry periods. Prune lightly in early spring to maintain shape if desired. Monitor for spider mites in warm climates.

3

Mature Form

Years 5 onward

Plant reaches mature height of 6-8 feet with pyramidal shape; foliage is dense and feathery with strong blue-gray and winter purplish coloring

Reduce watering frequency once established. Light pruning in spring maintains desired form. Ensure good air circulation to prevent disease.

4

Winter Dormancy

November-March (varies by region)

Foliage develops purple, bronze, or plum tones in response to cold temperatures; growth slows considerably

Reduce fertilizing. Provide shelter from harsh winds in exposed locations. No major pruning during winter.

Fun Facts

  • 🌱 Boulevard falsecypress develops striking purple or bronze foliage in winter, a color change caused by the production of protective anthocyanin pigments in response to cold temperatures.
  • 🌱 The soft, feathery foliage is different from the scale-like foliage typically associated with adult falsecypresses, as Boulevard retains its juvenile foliage characteristics throughout its life.
  • 🌱 Despite its common name referencing 'cypress,' this plant is not a true cypress but belongs to the Chamaecyparis genus, which are often called 'false cypresses' to distinguish them from true cypresses in the Cupressus genus.
