In contrast to spruces, fir cones are erect; they do not hang, unless heavy enough to twist the branch with their weight. The mature cones are usually brown. When young in summer, they can be green: A. grandis, A. holophylla. or reddish: A. alba, A. cephalonica, A. nordmanniana. or bloomed pale glaucous or pinkish: A. numidica, A. pinsapo
The scale bracts are hidden under the cone scales. The seeds, 8–9 mm (5 ⁄ 16 – 3 ⁄ 8 in) long with a wedge-shaped wing 1.5 cm (5 ⁄ 8 in) long, are released after the cones disintegrate at maturity in October. Manchurian fir is sometimes, but not commonly, used as an ornamental plant. [1]
Fraser fir is monoecious, meaning that both male and female cones occur on the same tree. [11] Cone buds usually open from mid-May to early June. Female cones are borne mostly in the top few feet of the crown and on the distal ends of branches. Male cones are borne below female cones, but mostly in the upper half of the crown.
Abies magnifica, the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States. It is a high-elevation tree, typically occurring at 1,400–2,700 metres (4,600–8,900 ft) elevation, though only rarely reaching tree line .
The male cones are 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) long, and are typically restricted to, or more abundant on, lower branches. Pollen cones develop over 1 year and wind-dispersed pollen is released for several weeks in the spring. Rocky Mountain Douglas-fir cones Left: Shuswap Lake, British Columbia, Canada
Coast grand fir. Coastal lowland forests, at sea level to 900 m altitude, from Vancouver Island and coastal British Columbia, south to Sonoma County, California. A large, very fast-growing tree to 70 m tall. Foliage strongly flattened on all shoots. Cones slightly narrower (mostly less than 4 cm broad), with thinner, fairly flexible scales.
