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.
