How to identify Himalayan pine (Pinus wallichiana)
Himalayan pine, also known as Blue pine, Wallich's pine
Himalayan pine is characterized by its sturdy evergreen nature and broad base. The tree sports horizontal lower branches, which are often retained as it matures. The growth pattern is upright with a loose, broadly pyramidal shape in its youth, transitioning to a more rounded crown in its older years. The branches are distinctive for being wide-spreading and pendulous. The plant prefers to be transplanted while young for optimal growth. Notably, it can suffer from discoloration in extreme winter conditions.
Lifespan: Perennial
Plant Type: Tree
Leaf Type: Evergreen
Sturdy evergreen with broad base and pendulous branches.
Distinctive blue-green needles, silvery blue underside, pendulous older needles.
Bark transforms from smooth gray to deep fissures, then rich dark brown.
The leaves of himalayan pine appear as 5 to 8 inches (12.7 to 20.3 cm) long soft needles, grouped in bundles of five. They are blue-green on the upper surface and exhibit a blue-white lower surface, creating a silvery blue cast. Young needles are erect, while older needles tend to droop, often bending near the base and producing a pendulous effect, making them a key feature for identification.
Himalayan pine produces inconspicuous flowers often ignored in favor of its prominent cones. The male flowers are small, cylindrical, and yellowish-brown, clustered at the base of new shoots. Female flowers are equally unobtrusive, typically reddish to green when young, and develop into the characteristic 6 to 12 in (15 to 30 cm) pendulous cones. These cones, which turn brown with age, develop from the female inflorescences over several growing seasons, releasing seeds upon maturation.
