Description
Silver Birch is a medium-sized deciduous tree, typically reaching 1525 metres (4982 ft) tall (exceptionally up to 39 metres (128 ft), with a slender trunk usually under 40 centimetres (16 in) diameter, but exceptionally to 1 metre (3.3 ft) diameter, and a crown of arched branches with drooping branchlets. The bark is white, often with black diamond-shaped marks or larger patches, particularly at the base. The shoots are rough with small warts, and hairless, and the leaves 37 centimetres (1.2 2.8 in) long, triangular with a broad base and pointed tip, and coarsely double-toothed serrated margins. The flowers are wind-pollinated catkins, produced before the leaves in early spring, the small 1-2mm winged seeds ripening in late summer on pendulous, cylindrical catkins 24 centimetres (0.79 1.6 in) long and 7 mm broad
The closely related Betula platyphylla in northern Asia and Betula szechuanica of central Asia are also treated as varieties of silver birch by some botanists, as B. pendula var. platyphylla and B. pendula var. szechuanica respectively (see birch classification).
B. pendula is distinguished from the related downy birch (B. pubescens, the other common European birch) in having hairless, warty shoots (hairy and without warts in downy birch), more triangular leaves with double serration on the margins (more ovoid and with single serrations in downy birch), and whiter bark often with scattered black fissures (greyer, less fissured, in downy birch). It is also distinguished cytologically, silver birch being diploid (with two sets of chromosomes), whereas downy birch is tetraploid (four sets of chromosomes). Hybrids between the two are known, but are very rare, and being triploid, are sterile.The two have differences in habitat requirements, with silver birch found mainly on dry, sandy soils, and downy birch more common on wet, poorly drained sites such as clay soils and peat bogs. Silver birch also demands slightly more summer warmth than does downy birch, which is significant in the cooler parts of Europe. Many North American texts treat the two species as conspecific (and cause confusion by combining the downy birch's alternative vernacular name 'white birch', with the scientific name B. pendula of the other species), but they are regarded as distinct species throughout Europe
