Lithocarpus densiflorus
Tanbark Oak, Quercus densiflora
| Some 100 species of these oak-like evergreens grow throughout Asia and Indo-Malaysia. The United States claims just one native: Lithocarpus densiflorus. Though not true Oaks, their rock-hard acornlike nuts, sometimes-toothed leathery leaves, and overall appearance have earned their common name. They may be an evolutionary link between Oaks (Quercus) and Chestnuts (Castanea) -- the spiky flowers or catkins look like Chestnut blossoms. Like Oaks, they tolerate a broad range of conditions, from wet watersides to rocky outcrops, but are not as cold-tolerant. A few United States nurseries carry species such as Lithocarpus edulis (Japanese False Oak). Small and attractive, with smooth blue-gray bark, it blooms lavishly. Lithocarpus henryi, with stunning 12-inch-long, bamboolike leaves, seldom exceeds 20 feet in cool temperate climates. Give full sun or light shade. Best in fertile, deep soil with medium drainage. Need little water once established. |
The red-brown bark, once used to tan leather, becomes deeply fissured in older trees. Oregon's champion Tanbark Oak towers 145 feet.
