Native to (or naturalized in) Oregon:
- Deciduous conifer, 70-90 ft, [21-27 m], open and pyramidal, drooping branches, short spur shoots. Leaves (needles) in clusters, as many as 40 per bundle arise from each spur, 2.5-4 cm long, deep green, yellowish in fall.
- Sun, sufficient moisture and well-drained soil. Similar to L. decidua but more tolerant of poor soils. Considered the best among the larches but its large size makes it most suitable for parks, golf courses, etc. However, there are selections available which are suitable for more limited space. The contorted selection, 'Diana', may only grow to a height of 20 ft (6 m) and 'Jacobsen's Pyramid', a narrow columnar form may reach 12 ft (3.6 m) in 10 years..
- Hardy to USDA Zone 4 Native to Japan.
- kaemferi: after Engelbert Kaempfer (1651-1716), physician and botanist who traveled in Japan.
