Common Alder (Alnus Glutinosa) – Sold in Bundles of 50

Common in wet ground, marshes and stream-sides. Rounded leaves are light green. Flowers’ green catkins (Feb – March) become black when ripened a year later. Fast growing. Grows to a max of 20m. The leaves have shallow, irregular teeth and remain on the tree quite late in autumn when they shed and fall. 

Due to an unusual bacteria in the tree, the Alder can improve the fertility of the soil and, as a pioneer species, help other species around it to colonise and establish themselves.
