Larix occidentalis Western larch Deciduous tree (1 Page of 5) The Larix occidentalis plant species is found in Western N. America - British Columbia to Montana, south to Washington and Oregon. It is a member of the Pinaceae family. Common gardeners may know the plant as Western larch. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Larix occidentalis Common Name: Western larch Family: Pinaceae Author: Nutt. Known Hazards: None known Mature Height: 45 Mature Width: Habitat: Mountain valleys and lower slopes, often in swampy areas, usually in mixed stands[60].
Cultivation Notes: Prefers an open airy position in a light or gravelly well-drained soil[200]. Plants are intolerant of badly drained soils, but they tolerate acid and infertile soils[200]. Succeeds on rocky hill or mountain sides and slopes[200]. A north or east aspect is more suitable than west or south[1].
This is a very cold-hardy species when fully dormant, but on the whole the trees are a disappointment in Britain. They are often excited into premature growth in this country by periods of mild weather in the winter and are then subject to damage by late frosts and cold winds. They also often suffer from canker and die-back[185]. Good trees, however, can be very good and fast growing, often putting on new annual growth of 1 metre when young[185].
Older trees develop a very thick bark, which protects them from forest fires[226].
Hybridizes freely with other members of this genus[200].
Open ground plants, 1 year x 1 year are the best for planting out, do not use container grown plants with spiraled roots[200]. Plants transplant well, even when coming into growth in the spring[200].
Plants in this genus are notably resistant to honey fungus[200].
