Betula medwediewii Medwediew's birch, Transcaucasian birch

In its natural habitat a multiple-stemmed shrub to average-sized tree. Sometimes up to 20 m high. Little used in cultivation and remaining smaller, usually growing into a sizeable shrub. The wide, almost round crown consists of stiff, upright growing branches that colour from yellow white to grey brown and mature trunks flake. Young twigs turn from brown into grey brown with striking lenticels. The buds on the thick twigs are sticky. The leaf diminishes in size as the tree matures. Sprouts late in spring but retains its leaves well into autumn. The inflorescence too, appears later than with most other birches. As the catkins of this birch are relatively big, it is often compared to an alder. Striking yellow autumn colour. Shallow rooting. Preferably a sheltered location.
