The female cone (megastrobilus, seed cone, or ovulate cone) contains ovules which when fertilized by pollen become seeds. The female cone structure varies more markedly between the different conifer families and is often crucial for the identification of many species of conifers.
When to Transplant Seedlings Outdoors. Timing your indoor planting schedule to perfection is the first step. But seeds started indoors will eventually need to be transplanted outside into your garden.
[citation needed] The cones, which contain the seeds (or nuts), of the Swiss pine are 4 centimetres (1.6 in) to 8 centimetres (3.1 in) long. Cones take 2 years (24 months) to mature. The 8 millimetres (0.31 in) to 12 millimetres (0.47 in) long seeds have only a vestigial wing and are dispersed by spotted nutcrackers. The species is long-lasting ...
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.

Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling.
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]
The cones thus grow over a two-year (26-month) cycle, so that newer green and older, seed-bearing or open brown cones are on the tree at the same time. Open cone with empty pine nuts. The seed cones open to 6–9 cm (2 + 1 ⁄ 4 – 3 + 1 ⁄ 2 in) broad when mature, holding the seeds on the scales after opening.
Place the seeds on a baking sheet and top with the sweet or savory spices. Give them a good mix to make sure the seeds are evenly coated. Roast in the oven for 10-15 minutes.
