Japanese Larch is a handsome deciduous conifer, not very different from the European species that is more commonly planted in the Midwestern and Eastern USA. Both develop a good golden-bronze autumn color before the needles fall. There are about 40 needles on each short spur on the twig. I notice these larch as being mostly planted in affluent neighborhoods or in parks. Most cities and bigger towns will have some planted somewhere in the municipality. The foliage of the Japanese species is at least somewhat bluish and its mature bark is different, often considered as prettier than the European species. The cones are 1 to 1.5" long and the tips of the cone scales are recurved or rolled back. Some big nurseries offer this Japanese species here and there.

Showy in the spring but tends to become unruly towards late summer.
Will not tolerate pruning out of season. I found that if I tolerate it's unruliness and prune only when proper it rewards with a lovely spring display year after year. Loves the sun and needs to dry out slightly between waterings. I also found it can be sensitive to wiring if not well acclimated. Becomes bare in winter after a 'mustard yellow' coloration before it's needles drop in fall.

Excellent bonsai specimen. Bark is a lovely rust color and peels beautifully. Branches arch slightly downward. Fantastic form.

Nice tree for bonsai. Does not tolerate standing water, but likes moist soil. Seed can be gathered from cones which ripen in late autumn. Yes, it really is a deciduous conifer.
