Fun Facts

🌱 Hinoki Cypress is native to Japan where it is considered sacred and has been cultivated for over 1,000 years; the name 'hinoki' means 'fire tree' in Japanese, referring to its traditional use for making fire-starting implements.
🌱 The 'Nana Gracilis' cultivar was developed in Japan and grows so slowly that a 20-year-old specimen may only reach 3-4 feet, making it exceptionally long-lived as a miniature conifer.
🌱 Unlike many conifers, Dwarf Hinoki Cypress cannot regenerate from pruning into bare wood, so careful, light pruning is essential to maintain its shape throughout its life.
