Years 5-15Tree becomes fuller and reaches substantial height; foliage becomes denser; winter color bronzing becomes more pronounced
Water during dry spells. Minimal pruning needed to maintain shape; avoid heavy pruning as it doesn't recover well. Remove any dead or diseased branches. Watch for bagworms.
Maturity
Years 15+ (long-lived, 50+ year lifespan possible)Tree reaches full height (15-25 feet depending on variety); dense, columnar form; rich green summer color with bronze winter tones

Fun Facts
- 🌱 Columnar Cryptomeria is native to Japan, where it is called 'sugi' and is the national tree of Japan; it has been planted around temples and shrines for over 2,000 years.
- 🌱 The feathery, soft foliage that appears delicate is actually quite hardy; the needles are modified leaves that give the tree its distinctive texture and contribute to its bronzy winter coloration due to stress-induced pigment changes.
- 🌱 Some Cryptomeria specimens in Japan are over 1,000 years old and can reach heights exceeding 160 feet, making them among the tallest trees in Japan; cultivars like 'Elegans Compacta' are much more modest, rarely exceeding 25 feet.
