- 🌱 The foliage changes color seasonally, displaying blue-green tones in spring and summer, then shifting to bronze or purple-bronze in fall and winter, providing year-round color without flowers.
- 🌱 Despite its slow growth rate, Ellwood's Hinoki eventually reaches 12-20 feet tall but maintains a width of only 2-3 feet, making it exceptionally space-efficient for vertical gardening.
