Opinion
"
This species was thought to be extinct for millions of years. Such a wonderful specimen to see in the full sun. Sun radiates through foliage and appears to glow with gold colours. Excellent display of bark in winter, reddish browns and formed ridging at base of trunk make it visually appealing in dormant months. This huge tree is said to reach heights of 30 m if given proper attention. Needs little attention to pruning, growing in a uniform shape.
