Belfast Botanic Gardens Tree Archive

This series of short articles about trees in the Belfast Botanic Gardens is compiled by members of the Friends group and Gardens staff. We aim to build up to a comprehensive archive of trees in Belfast Botanic Gardens. Each article illustrates a tree growing in Belfast Botanic Gardens together with information from a range of sources. Where possible we will give the tree tag number - these are the small aluminium discs, usually fixed on the tree trunk, 2 to 3m above ground level.

Silver birch (Betula pendula) is native to almost all of the British Isles, although commoner in the south, preferring drier and acid soils. The leaves are toothed with large and small teeth, taper to a sharp point and are without hairs. These characters distinguish the silver birch from the downy bitch (Betula pubescens) which has a more rounded tip to the leaf and hairy leaves. The female catkins of silver birch stick up from the hanging branches while the male catkins hang down. There are several fine specimens in Belfast Botanic Gardens, one close to the Botanic Avenue gate (photographed here) and another by the gate into the garden works yard.
