Ornäs birch trees grow to a height of 20–25 metres, and have a rounded, somewhat uneven crown. The main branches have an acute angle to the trunk, and only the outermost branches are hanging. The Ornäs birch is often confused with the similar birches "Betula pendula" 'Crispa' and "Betula pendula" 'Laciniata', and all three varieties are sometimes sold commercially as "Swedish birch". The genuine Ornäs birch can be distinguished by its growth-form, and in that its leaves are more deeply indented than the other varieties.
