Description and Growing Information

General DescriptionLarge pyramidal evergreen with beautiful bright yellow shoots of new growth. Often has several trunks with deeply furrowed, reddish-purple bark.
ID CharacteristicBright yellow shoots of new growth that contrast with the dark green mature growth. The yellow shoots keep their colour well into the summer.
ShapeLarge, upright, weeping, pyramidal habit. Lower branches become quite pendulous as the tree matures.
LandscapeBeautiful specimen tree as the bright yellow growth lasts well into the summer and the soft, feathery foliage will provide winter interest. Perfect when used as a privacy screen, and can also be pruned into a hedge.
CultivationGrow in moist, well-drained soil, pH should range from acidic to slightly alkaline. Tolerates shade quite well, but will do best in partial shade. Will not tolerate compacted soils, wind, or drought, and has the potential to suffer from sun scorch.
PestsWoody adelgid, scale, and mites have become a common problem. Also suffers from blight, rust, and butt rot.
HabitatHorticultural origin.
Bark/Stem DescriptionScaly in youth, but becomes deeply furrowed as it matures. Outer bark is reddish purple.
Flower/Leaf Bud DescriptionLight brown, minute and ovoid shape with small fuzzy scales.
Leaf DescriptionSmall, flat, ovoid needles arranged in groups of 2.
Flower DescriptionInconspicuous, flower is sterile.
Fruit DescriptionSmall, ovoid cones with rounded scales.
Colour DescriptionNew growth emerges as a bright yellow which will last well into summer, contrasting beautifully with the dark green colour of the more mature foliage.
Texture DescriptionThe small needles make this a very fine textured plant.
