Fun Facts

🌱 Crippsii is a Japanese cultivar meaning 'golden' in reference to its striking golden-yellow foliage, which is brightest in full sun and becomes more green-gold in shade.
🌱 This tree grows extremely slowly—typically only 4-6 inches per year—making it ideal for gardeners seeking a long-lived, low-maintenance specimen that won't outgrow its space.
🌱 Hinoki cypress has been cultivated for centuries in Japan, where it is considered a sacred timber and is used in temple construction and traditional woodworking for its aromatic, durable wood.
