How to Grow Dwarf Hinoki Cypress Crippsii

Dwarf Hinoki Cypress Crippsii

Chamaecyparis obtusa 'Crippsii'

shrub

Crippsii is a compact, slow-growing cultivar of Hinoki cypress featuring bright golden-yellow foliage that maintains its color year-round. It develops a dense, pyramidal form reaching 10-15 feet tall and 6-8 feet wide at maturity, making it ideal for specimen plantings and smaller landscapes. The soft, feathery foliage is aromatic and becomes more golden in full sun exposure.

Growing Conditions

☀️

Sun: Full sun to partial shade; needs 4-6 hours of direct sunlight daily for optimal golden color (less sun results in greenish foliage)

Growth Stages

Establishment

First year

Young transplant with initial root development and adjustment to landscape conditions

Water consistently, mulch around base (2-3 inches), protect from harsh winds and winter sun scald during first year. Avoid fertilizing the first season.

Vegetative Growth

Years 2-4

Rapid development of branching structure and dense foliage; pyramidal form becomes evident

Continue regular watering during dry spells. Light pruning can shape form if desired. Maintain consistent moisture, as drought stress causes browning.

Maturing

Years 5-10

Plant approaches full size with tightly branched, dense golden foliage and established branching pattern

Minimal pruning needed; remove any dead or diseased branches. Reduce watering frequency as roots deepen. Monitor for spider mites in hot, dry conditions.

Established

Year 10 onward

Mature specimen with stable size (10-15 feet), dense pyramidal form, and vibrant golden color maintained year-round

Water only during extended drought. Remove any winter damage or diseased foliage in spring. Avoid pruning extensively to maintain natural form. Minimal maintenance required.

Avoid planting near:

Walnut trees (juglone toxicity) Highly competitive large shrubs Plants requiring very moist soils in poorly draining areas

Common Pests

Spray with water to dislodge; apply neem oil or insecticidal soap in hot, dry conditions. Increase humidity around plant.
Hand-pick bags in late fall or early spring; spray with Bacillus thuringiensis (Bt) in early summer when caterpillars are small.
Prune affected branches 6 inches below visible damage; sterilize tools between cuts. Improve air circulation and avoid overhead watering.
Ensure excellent drainage; avoid waterlogging. Remove affected plants if severe. Improve soil drainage with amendments.

Fun Facts

🌱 Hinoki cypress is native to the mountainous regions of central Japan, where it has been revered in Japanese gardens and temple landscapes for centuries; 'Crippsii' was selected and named as a cultivar for its superior golden coloration.
🌱 The foliage contains aromatic oils that release a pleasant, slightly spicy fragrance when brushed or warmed by sun, making it pleasing to touch and smell in the landscape.
