Dahurian Larch (Larix Gmelinii) 20 seeds (#44)

Dahurian larch is a deciduous conifer that is native to northeastern Siberia. Bright green needles turn yellow in fall before falling to the ground.
This is a tree of very cold climates, ranging northward inside the Arctic Circle to tree line. In the wild, it grows to 12-18 m (40-60') tall with a broad conic but open crown and horizontal branching. In the far northern areas of its range, it grows much smaller and shrubbier as it approaches tree line areas. Needles to 4 cm (1 1/2") long in brush-like clusters appear at the ends of spur-like shoots along the branches. Cones 4 cm (1 1/2") emerge purple but mature to light brown.
Bark is rusty brown.
Best grown in moist, acidic, well-drained soils in full sun. Tolerates some light shade. Intolerant of full shade, dry soils and most city pollutants. Best performance is in temperature conditions that mirror its native habitat, namely, cool summers and cold winters. Trees perform poorly in hot and humid summer conditions south of USDA Zone 5.

GERMINATION INSTRUCTIONS
Seed - sow late winter in pots in a cold frame. One months cold stratification helps germination.
Seeds need 30 days pre-chill period. Seeds can be stratified in dampened peat or sand, in a plastic box or bag at +4-+5C in a refrigerator. The seeds should not be frozen or in a wet medium.
It is best to give the seedlings light shade for the first year. As soon as they are large enough to handle, prick out the seedlings into individual pots. Although only a few centimetres tall, they can be planted out into their permanent positions in the summer providing you give them an effective weed-excluding mulch and preferably some winter protection for their first year. Otherwise grow them on in the cold frame for their first winter and plant them out in early summer of the following year.
