Thuja occidentalis 'Nigra' (Dark Green Arborvitae) Unity Grown

Thuja occidentalis 'Nigra' is an attractive, dark-green cultivar of arborvitae that is well suited for use in the home garden due to its dark green, glossy, evergreen foliage and its medium to large height of 15-18' at maturity. While 'Nigra' may have a mature spread of 8-10' feet wide, larger than some arborvitae cultivars, this width makes 'Nigra' a great choice for well-spaced hedge and border plantings, especially along property lines. Dense, feathery foliage also makes 'Nigra' an excellent specimen tree, retaining its color better during the winter months than other arborvitae varieties.

'Nigra' arborvitae prefers full sun and partial shade, though areas with too much shade may result in more sparse growth. Requiring not much beyond average soil moisture and a wll-draining site, these hardy specimens can tolerate deer damage, cold, and drought once established. While some arborvitae is generally considered deer resistant, it is certainly not deer proof, and other varieties like the western arborvitae (Thuja plicata) are more deer resistant during harsh winters where other food sources are scarce. Although it does not flower, Thuja occidentalis 'Nigra' attracts small birds and wildlife by offering cover, shelter, and small edible cones; 'Nigra' also acts as a host plant for a variety of moth and butterfly larvae which birds can help keep in check.
