Alnus cordata – Italian alder

View prices and availability
Alnus cordata is indigenous in Italy and parts of Greece. It is a fast-grower that can eventually attain a height of 15 m. The almost horizontal growth of the side branches is characteristic. From the scattered buds, on short stalks, the leaves appear. They are heart-shaped and 12 cm long. The topside is green and glossy. In autumn they remain long on the tree. As soon as winter ends the female and male, pendulous catkins appear. They are followed by the familiar strobiles, which, arranged in clusters, appear from September onwards and remain on the tree all winter. The tree is shallow-rooting and not deep with many delicate rootlets. Little susceptible to sea wind, tolerant to paving.
Our trees can only be planted when they don't have any leaves. Due to the this we will start delivering again from November 2024.
