Description:

Form: Pyramidal, Upright or erect.

Characteristics:

Abies lasiocarpa is an evergreen Tree growing to 25 m by 4 m at a slow rate.
It is hardy to zone 5 and is not frost tender. It is in leaf all year, and the seeds ripen in September. The species is monoecious and is pollinated by Wind.
Suitable for: light , medium and heavy soils and can grow in heavy clay and nutritionally poor soils. Suitable pH: acid and neutral soils. It can grow in full shade semi-shade or no shade. It prefers moist soil.

Cultivation:

Landscape Uses:Screen, Specimen. Prefers a good moist but not water-logged soil. Grows well in heavy clay soils. Very shade tolerant, especially when young, but growth is slower in dense shade. Intolerant of atmospheric pollution. Prefers slightly acid conditions down to a pH of about 5. Prefers growing on a north-facing slope. Occasionally planted for timber in N. Europe but this species does not thrive in Britain. It is a very cold-hardy tree but the milder winters of this country make it susceptible to damage by aphis and late frosts. The sub-species A. lasiocarpa arizonica. Lemmon. is growing somewhat better here. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm in height. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. The crushed foliage has a balsam aroma. Special Features:North American native, There are no flowers or blooms.

Habitats:
Often found in poor and rocky soils
it is rarely seen below 600 metres. It grows in forests right up to the timber line where it is no more than a shrub on exposed slopes at high altitudes.
