Cones are large, 15 to 23 cm (6 to 9 in) long, 5 to 8 cm (2 to 3 in) in diameter, and oblong cylindric in shape. Shasta red fir bracts are longer than the cone scales and are easily visible on the surface of a mature cone. California red fir bracts are shorter than the cone scales and are not visible on an intact cone.

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 .

Cones: The cones sit upright on the branch like other firs. The cones fall apart at maturity, leaving a cone core spike on the branch. Shasta red fir cones are larger than noble fir cones and have whiskery bracts that protrude beyond the scales, but the bracts are shorter than those of noble fir.

Apr 16, 2024 · It is sometimes confused with Pacific Silver Fir, but its cones are much larger with more conspicuous green bracts, and its bark develops grooves as it ages rather than plates. It can be differentiated from Red Fir by its green leaves that are not glaucous and its bark grooves that are not as widely separated as Red Fir.

Feb 10, 2025 · Seed cones oblong-cylindric, 14-23×6-9 cm in the type variety but 9-17×3-9 cm in var. critchfieldii, purple turning brown at maturity, sessile, apex round; scales ca. 3 × 4 cm, pubescent; bracts included (in the type variety) or exserted (var. critchfieldii).

Mar 7, 2013 · Shasta red fir (Abies magnifica var. shastensis) occurs from Lassen Peak to Crater Lake National Park and has cones with partly exerted bracts. The second variety, A. m. var. magnifica, exists in the northern and central Sierra Nevada and has a hidden-bract cone type.

Mar 24, 2022 · Cones on noble firs are long and cylindrical and can grow to between 4” and 9” (10 – 22 cm) long. These fir cones are yellowish-green when immature and gradually turn brown. The bark of noble fir trees is reddish-brown when mature. Fir tree identification. Noble firs grow to between 130 and 230 ft. (40 – 70 m) tall.

Shasta red fir cones open and are pollinated in mid- to late June, and cones ripen in late September. Seed dispersal occurs in late September to mid-October [26,64]. FIRE ECOLOGY SPECIES: Abies magnifica

owering and Fruiting-Red fir is monoecious. Male strobili (cones) are small-generally less than 1.6 cm (0.6 in) long-deep purple-red, and densely clustered on the u. derside of l-year-old twigs about midcrown. Female cones are borne erect on old branches in the uppermost crown, although both male and female cone.

Red Fir cones are from five to eight inches long and about half as wide. White Fir cones are from three to five inches long. One of the charms of driving to Glacier Point comes from the view of the forests of Red Fir seen along the way.
