Thuja occidentalis Holmstrup (American Arborvitae)

Award-winning Thuja occidentalis 'Holmstrup' (American Arborvitae) is a medium-sized, evergreen shrub of dense, narrow, upright habit with vertical sprays of rich green foliage that holds its color well in cold winters. Slow-growing, about 8-12 in. per year (20-30 cm), this pretty conifer is a popular choice for use in a border or as a focal point in a small garden. Ideal for making a low hedge.
