Colorful and versatile, Thuja occidentalis (American Arborvitae) is a dense, conical to columnar, evergreen tree with flat, spreading sprays of aromatic, scale-like foliage. Rich green to blue-green in summer, the foliage often turns yellowish green to brownish green in winter, particularly if the plant is exposed to winter sun and wind. It can be single- or multi-trunked and its gray-brown to gray bark exfoliates on mature branches and trunks, revealing the reddish bark underneath. Forming a majestic exclamation point in the landscape, it is reliable and cold weather resistant. Slow-growing and long-lived (up to 1,500 years!), American Arborvitae if perfect for use as a specimen, screen or hedge, around foundations and in groupings. This highly aromatic conifer provides food and cover for many species of birds.

  • Grows up to 20-40 ft. tall (6-12 m) and 10-15 ft. wide (3-5 m).
  • A full sun lover, this plant is easily grown in average, moist, well-drained soils. Usually appreciates some light afternoon shade in hot summer climates. Bear in mind that foliage density loosens up in too much shade. Tolerates a wide range of soils including heavy clay, almost pure sand, gravelly soils, moderately dry soils, and wet soils. Intolerant of dry conditions. Protect from drying winds, especially when young.
  • May be affected by leaf blight, canker, leaf miner, bagworms, mealybug, scales and spider mites. Deer browse can be a serious problem.
  • Low maintenance, American arborvitae tolerates shearing well for a more tailored shape. Prune in early spring before onset of new growth. Provide a generous root zone mulch
  • Propagate by semi-hardwood cuttings
