Description Ellwood Lawson Cypress is known for its soft, feathery blue-grey foliage and its upright columnar growth habit.

  Morphology:
This coniferous tree grows to height of 10’-15’ but stays narrow over time. The ascending branches are densely arranged supporting fragrant, awl-like needles which often turn a pleasing steel blue color in the winter. The needles are arranged oppositely on the slender twigs.

Under exposed or windy conditions some of the branches can break out of their upright growth habit. Gardeners my need to remove these limbs.

  Adaptation:
Ellwood cypress does best in full sun to partial shade in moist well-drained, acidic soils. In areas west of the Cascade Mountains, it grows well with the higher relative humidity.

While normally used as a single accent plant, this cultivar could be grown together to form a hedge.

  Pests:
Spider mites may be an issue with dry sites.
