Description
Thujopsis dolabrata 'Nana' Shrub | Hiba arborvitae
The Hiba arborvitae shrub is a compact, bushy evergreen conifer with green foliage and slow growth. Its botanical name is Thujopsis dolabrata 'Nana', and it is also known as Japanese hiba. This product is sold in shrub form, so its compact habit gives it a different garden presence from other forms of the plant. It reaches an average mature height of about 100 cm; this is an average, not a guaranteed size or a stated growing time. No mature width is supplied. The green foliage stays on the plant through the year, giving it an evergreen presence in the garden. Its flowers are inconspicuous, so they do not create a showy display. The plant is listed as low-maintenance, though it still needs suitable growing conditions. Fruit-bearing is indicated, but no further details about the fruit are supplied. For UK gardens, consider a sheltered position with well-drained, humus-rich soil that remains slightly moist. This slow-growing shrub may suit gardeners looking for an evergreen plant with a compact, bushy habit rather than a tree form.
