Description and Growing Information
General Description | Large pyramidal tree, very dense, nearly vertical branching system that fattens out with the foliage. Small blue fruit that turns reddish brown in the autumn. The fruit does not hold much interest in the autumn. |
Shape | Conical or columnar, branches grow nearly straight upwards. Very large dense tree. |
Propagation | Germination by seed is low due to poor viability; the seed is thin and weak. This tree can be propagated by cuttings taken in the autumn. Cuttings taken in October that are placed in a sand peat moss mix root very easily. |
Cultivation | Prefers well drained moist soil; full sun or partial shade; protection from cold winds; and lower night temperatures. If transplanted it is best balled and burlapped. Neutral to acidic soils are preferred. It will grow thin with poor colour in densely shaded areas. |
Pests | Relatively pest and disease free, but a fungus called Phytophthora lateralis is rapidly killing these trees in the mountainous regions of Oregon and Northwest California. This fungus rots the roots and can completely kill these trees. |
Notable Specimens | Wakehurst Place, Ardingly, Haywards Heath, Sussex, England. |
Habitat | Horticultural origin. |
