General tree description

Alnus hirsuta is a medium sized tree, up to 20 metres tall, with smooth grey-brown bark. It has broadly ovate leaves which are rounded to wedge-shaped at the base. They are 6 to 12cm long and nearly as wide, somewhat lobed, doubly toothed, dull dark green and slightly downy above and hairy beneath. Male flowers (yellow- or red-brown catkins) open in mid winter. Tiny red-purple female catkins appear at the shoot tips in early spring and ripen to form woody cone-like structures from which seeds are released.
