High Quality Content by WIKIPEDIA articles! Betula nana (Dwarf Birch) is a species of birch in the family Betulaceae. It is a shrub growing to 1-1.2 m high. The bark is non-peeling and shiny red-copper colored. The leaves are rounded, 6-20 mm diameter, with a bluntly toothed margin. The leaves are evergreen, an adaptation to the cold climate, it is believed, which allows photosynthesis to begin without first having to grow new leaves. The fruiting catkins are erect, 5-15 mm long and 4-10 mm broad.
