General Description | Alnus nitida has green leaves with brown catkins and grows by river banks and streams of the Himalayas, growing to a good height and producing bark that can be used for dyes and swelling treatment. This tree is on the IUCN Red List, but due to a lack of threats has been labelled 'Least Concern'. |
ID Characteristic | Alnus nitida will be around 25 m tall with smooth but fissured bark, leading to branches of oval-shaped buds, catkins, and simple elliptical leaves. |
Shape | Alnus nitida is an upright tree. |
Landscape | This tree is cultivated as one of Pakistan’s roadside trees. |
Propagation | Seeds are best sown in a cold frame and should start to germinate during spring as weather warms. When grown large enough, choose seedlings for individual pots. Semi-hardwood cuttings from mature Alnus nitida are taken when autumn begins. |
