Alnus sieboldiana Alder

Description: Alnus sieboldiana is a large, handsome variety with green leaves that have toothed margins. Very showy male catkins in spring with prominent yellow anthers and large female cone-like fruits in the autumn. Deciduous but leaves remain until December. Native to Japan.

Alnus Growing Tips: Will tolerate almost any soil condition except shallow chalk. Fast and easy to grow, thriving even in waterlogged soil. Excellent for shelter belts. Respond well to coppicing and heavy pruning at any stage. Should be encouraged as shelter trees on poorland as they are effective nitrogen fixers for other symbiotic plant life.
