#317 (A17) WHITE HIMALYAN BIRCH
Betula utilis var. jacquemontii
      Planted: 1995
This tree is in the centre, to the south of the Malus Avenue.
Purchased from Hillier Nurseries, Romsey, Hampshire in December 1995.
Betula utilis is native to the western Himalayas , growing at elevations up to 4,500 m. The Latin utilis means “useful”, and refers to the many uses of the different parts of the tree. The white, paper-like bark was used in ancient times as a writing surface for manuscripts of Sanskrit. Selected varieties are used for landscaping even while some areas of its native habitat are being lost due to overuse of the tree for firewood.
Described and named by botanist David Don (1799 – 1841) a Scottish botanist in 1825. Specimens collected by Nathaniel Wallich (1786 – 1854) a Danish surgeon and botanist, from Nepal in 1820.
A Deciduous tree with white, paper-like bark Close-up showing lenticels.
In native habitat, forms forests, growing as a shrub or tree reaching up to 20 m tall.
Leaves are ovate, 5 to 10 cm long, with serrated margins, and slightly hairy. Flowering occurs from May to July, with only a few male catkins, and short, single (sometimes paired) female catkins. The perianth has four parts in male flowers, and is absent in the female flowers. Fruits ripen in September and October.
The thin, papery bark is very shiny, reddish brown, reddish white, or white, with horizontal lenticels which peels off in broad, horizontal belts.
The wood is very hard and heavy, and quite brittle. The heartwood is pink or light reddish brown.
Many named varieties and cultivars are used in landscaping throughout the world. In the eastern end of the tree’s native distribution, several forms have orange or copper-coloured bark. Betula utilis var. jacquemontii, from the western end of the native habitat, is widely used because several cultivars have especially white bark.
