Overview
Cryptomeria japonica 'Cristata' is a medium-sized, evergreen coniferous tree in the family Cupressaceae, a cultivar of Japanese cedar exhibiting fasciation — a developmental mutation in which the growing tip flattens and widens, producing broad, fan-shaped, cockscomb-like crested branch tips. 'Cristata' means 'crested.' Trees grow 10–20 feet (3–6 m) tall and 6–10 feet (1.8–3 m) wide at a moderate rate of 8–12 inches (20–30 cm) per year, maintaining a broadly conical to irregular crown. The crested branch tips are flat, broad, and undulating — 1–3 inches (2.5–8 cm) wide at the growing tip, contrasting with the otherwise normal awl-shaped, spirally arranged needles on the non-fasciated portions of each branch. Degree of fasciation varies by branch and by season; some branches revert to normal growth. Foliage is dark green, bronzing in cold winters and recovering green in spring. Reddish-brown fibrous bark exfoliates in vertical strips. Small globular cones 0.5–1 inch (12–25 mm) with hooked scales. Non-toxic.
Native Range
Cryptomeria japonica 'Cristata' is a cultivar of Cryptomeria japonica, native to mountain forests of Japan and central-southern China. The fasciated form was selected from a natural mutation occurring in cultivation.Suggested Uses
Cryptomeria japonica 'Cristata' is planted as a specimen conifer in Pacific Northwest gardens and conifer collections where the fasciated branch tips provide visual interest at close viewing distance. The moderate size (10–20 ft / 3–6 m) suits medium to large residential settings. Educational value: fasciation as a developmental mutation; comparison with non-crested Cryptomeria cultivars.How to Identify

Bloom Information
Cryptomeria japonica 'Cristata' produces inconspicuous male and female cones. Male cones shed pollen in late winter to early spring (February–March). Female cones are small, globular, 0.5–1 inch (12–25 mm) with hooked scales, ripening brown in fall.Detailed Descriptions

Care & Maintenance
Care Guide
Plant Cryptomeria japonica 'Cristata' in full sun to partial shade in moist, well-drained, acidic to neutral soil with a pH of 5.0–7.0. Consistent moisture during the first two to three growing seasons. Tolerates brief drought once established. Performs well in Pacific Northwest maritime climate. Mulch the root zone to maintain soil moisture. The fasciation character is maintained through vegetative propagation — plants grown from seed may not exhibit crest. Degree of fasciation varies by plant and conditions; this is inherent to the cultivar.Pruning
No pruning is required to maintain form. Remove dead branches in late spring. Lower branches may be removed to expose the ornamental bark. Do not shear. Reverting non-crested branches may be removed if desired, though this is not necessary.Pruning Schedule
