Growth Stages

1

Establishment

1 year

Newly planted shrub with compact, pyramidal form and blue-gray foliage

Water regularly to keep soil moist. Mulch around base with 2-3 inches of organic material. Avoid pruning during first year; allow plant to establish roots.

2

Young Growth

2-3 years

Vigorous growth phase with increasing height and width, foliage becoming fuller

Continue consistent watering. Light shaping pruning can be done to encourage density. Fertilize lightly in spring with balanced, slow-release fertilizer.

3

Maturing

3-5 years

Reaches most of its final size with dense, well-defined pyramidal shape and rich blue-gray color

Maintain regular watering schedule. Prune to maintain shape if desired. Watch for spider mites in hot, dry conditions.

4

Mature

Indefinite; long-lived shrub

Fully developed shrub 3-6 feet tall with deep blue-gray summer foliage and purple-blue winter color

Water during dry periods. Minimal pruning needed; remove any dead or diseased branches. Fertilize sparingly. Foliage color intensifies with cool fall temperatures.

Companion Planting

Plan your garden →

Plant with:

Dwarf Alberta Spruce Japanese Boxwood Creeping Juniper Heuchera Ornamental Grasses Hydrangea Rhododendron

Avoid planting near:

Wet-loving plants (excessive moisture causes root rot) Plants requiring dry conditions (competition for water) Large aggressive shrubs (shading and space competition)

Common Pests

  • Spray with water to dislodge; use miticide if severe. Increase humidity and avoid drought stress. Predatory mites can provide biological control.

  • Hand-pick and destroy bags in winter. Apply Bt (Bacillus thuringiensis) in late spring when larvae emerge. Insecticidal spray in summer if needed.

  • Prune out infected branches and disinfect tools. Improve drainage and avoid overhead watering. Avoid wounding plants.

  • Improve soil drainage. Avoid overwatering. Remove affected plants if severe. Ensure well-draining soil at planting.

  • and

    Monitor regularly. Spray horticultural oil in dormant season. Apply neem oil or insecticidal soap during growing season if needed.

Fun Facts

  • 🌱 Boulevard Sawara Cypress is a cultivar of Chamaecyparis pisifera, a native Japanese species also called Hinoki false cypress, introduced to Western gardens in the 1800s.
  • 🌱 The foliage color intensifies and shifts to purple-blue during cold winter months due to the production of protective anthocyanin pigments, a natural antifreeze mechanism.
  • 🌱 Despite its delicate, feathery appearance, Boulevard Sawara Cypress is remarkably hardy and can withstand cold winters, making it suitable for northern gardens where true cypresses cannot survive.
