Western Larch

## Identification and landscape use Western larch (Larix occidentalis) is a large deciduous conifer whose soft needles turn golden before falling in autumn. It is native to parts of the inland Pacific Northwest and northern Rocky Mountains. This forest tree can exceed 100 feet and needs substantial space; it is generally too large for an average garden. [Oregon State University](https://landscapeplants.oregonstate.edu/plants/larix-occidentalis) describes its size and requirements. ## Growing conditions Choose a sunny site in a cool climate with moist, well-drained soil. The [US Forest Service](https://research.fs.usda.gov/silvics/western-larch) describes its preference for deep, moist soils and lower north- or east-facing slopes. Check local suitability and allow for seasonal needle drop and its mature canopy. ## Firewise source guidance The [Idaho BLM database](https://www.blm.gov/sites/default/files/documents/files/Fire%20Resistance%20of%20Plants%20Master%20Database.pdf) rates this species 4, using a 120-by-40-foot example and specifying full sun and medium water. Its conifer table calls for pruning lower branches and removing dead needles. Mature western larch can develop thick bark and a high crown that improve fire survival, but this does not guarantee survival or make all plantings safe; tree age, placement and maintenance matter.
