Description
Thuja occidentalis 'Filiformis' shrub C2 | Threadleaf arborvitae
Thuja occidentalis 'Filiformis' shrub is an evergreen Western arborvitae with a distinct, bushy outline. This is the shrub form, not a tree or hedge form. Its upright growth is shaped by hanging, thread-like shoots, which give the plant a recognisable silhouette. The foliage is green and remains on the plant throughout the year, bringing a steady evergreen presence to a garden. At maturity, it reaches an average height of about 250 cm; this is an average, not a guaranteed maximum. Its width has not been specified. Flowers are inconspicuous, so the fine, hanging shoots and green foliage provide the main visual interest. The plant is also listed as fruit-bearing, but no further details about its fruit are provided. It is considered low maintenance, although this does not mean it needs no care. In a UK garden, keep in mind its need for sufficient moisture and avoid a position exposed to drying winds. For more plants in the same genus, see Thuja.
