Winter sowing is a method of starting seeds outdoors in winter. This is generally done with seeds that require a period of cold stratification. The method takes advantage of natural temperatures, rather than artificially refrigerating seeds.
The Pinaceae (/ p ɪ ˈ n eɪ s iː ˌ iː,-s i ˌ aɪ /), or pine family, are conifer trees or shrubs, including many of the well-known conifers of commercial importance such as cedars, firs, hemlocks, piñons, larches, pines and spruces.
Jun. 21—It starts with the cones. They're usually gathered in the wild, from whitebark pine trees several thousand feet above sea level somewhere in the West. The cones get shipped to the U.S ...
The cones open to 4 to 6 cm (1 + 1 ⁄ 2 to 2 + 1 ⁄ 2 in) broad when mature, releasing the seeds immediately after opening. The seeds are 5 mm (3 ⁄ 16 in) long, with a 12 to 22 mm (1 ⁄ 2 to 7 ⁄ 8 in) wing; they are mostly dispersed by the wind, but some are also dispersed by Clark's nutcrackers. [citation needed]
In some cases, they will drop their seeds, but in most Pinus serotina, they will persist and hold their seeds. The color of the seed cones and seed scales is red-brown in color. The foliar sheaths measure 0.4 to 0.8 with long bases. The seeds are ovule in shape, being 0.2 and 0.24 in length, and have an angled tip colored a pale brown. [10]
The female seed cones are scaly, egg-shaped, and 10–15 cm (4–6 in) long by 7–11 cm (3–4 in) wide. The smaller, more numerous male pollen cones are at the tips of the branchlets and are scaly, foxtail-shaped, and 5 cm (2 inches) long.
