Abies procera

Form: Columnar, Pyramidal, Upright or erect.

Abies procera is an evergreen Tree growing to 60 m by 5 m at a medium rate.
It is hardy to zone 5. 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. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Screen. Prefers a good moist but not water-logged soil. Succeeds in cold exposed positions and in poor mountain peats. Succeeds in poor thin soils so long as sufficient moisture is present. Grows well in heavy clay soils. Plants are very shade tolerant, especially when young, but they grow more slowly in dense shade. Intolerant of atmospheric pollution. Prefers slightly acid conditions with a pH down to about 5. Grows well on a north-facing slope. A long-lived tree in the wild, with specimens more than 600 years old recorded. It is a very ornamental tree, but is very susceptible to damage by aphis in some areas of the country. Planted for timber in W. and N. Europe, in Britain it grows best in wetter parts of the country such as the Perthshire valleys of Scotland. Trees do not grow well in the drier areas of Britain. In a suitable site it can make new growth of 1 metre a year until it is 25 metres tall when growth slows. Exposure seems to severely limit growth in height in southern and eastern regions but less so in areas of high rainfall such as N. Wales and Argyll. New growth takes place from early June to August. 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. Trees are sometimes used as 'Christmas trees'. Plants are strongly outbreeding, self-fertilized seed usually grows poorly. They hybridize freely with other members of this genus. Special Features:Attractive foliage, North American native, There are no flowers or blooms.
