The Siberian Larch, or Russian larch, (Larix sibirica) is a frost-hardy tree which occurs naturally in northeastern Russia and western Siberia. It has been raised in Canada and in the northern United States, but only in a limited way. At maturity, the tree may attain a height of 130 feet (40 m). Siberia Siberia (Russian: , common English transliterations: Sibir’, Sibir; from the Tatar for “sleeping land”) is a vast region of Russia and northern Kazakhstan constituting almost all of northern Asia. ...

Larix sibirica was first cultivated in 1806. The minimum seed-bearing age is 12 years. Flowering dates are April to May. Male and female flowers are borne separately on the same tree. The male flowers are solitary, yellow, globose-to-oblong bodies that bear wingless pollen. The female flowers are small cones that ripen the first year. A ripe cone is made up of brownish, woody scales, each of which bears two winged seeds. The length of a cone is 1 to 1½ inches (2.54 to 3.81 cm), but the length of a seed is much less. Properly stored seeds remain viable for 25 years or more. 1806 was a common year starting on Wednesday (see link for calendar). ...

Genus Larix

Genus Larix includes ten species. The larches are cone-bearing, deciduous trees widely distributed over the cooler regions of the Northern Hemisphere. They grow in almost any kind of soil, including clay and limestone, but they develop best when grown in the open on somewhat moist, but well-drained soils. Because of its rot resistance, larch wood is especially valuable for posts, poles, railroad ties sleepers, and mine props. Deciduous means temporary or tending to fall off (deriving from the Latin word decidere, to fall off). ... The Northern Hemisphere is the half of a planets surface (or celestial sphere) that is north of the equator (the word hemisphere literally means half ball). On Earth, the Northern Hemisphere contains most of the land and population. ... Sleepers has several meanings: for the 1996 film, see Sleepers (film) for railway sleepers, see railroad tie Sleepers is also a solo album by rapper Big Pooh from the group Little Brother. ...

The larches hybridize readily. L. leptolepis X sibirica, known as L. marschlinsii Coaz, was originated in 1901. 1901 was a common year starting on Tuesday (see link for calendar). ...
