THUJA occidentalis 'Holmstrup'

Family

Cupressaceae

Botanical Name

THUJA occidentalis 'Holmstrup'

Plant Common Name

Eastern Arborvitae, White Cedar

General Description

It is likely that no native American evergreen is more prevalent in the North American landscape than arborvitae. The cultivar 'Holmstrup' is a compact dense narrowly pyramidal form of this eastern North American native. This slow-growing selection has flattened vertical fan-like sprays of soft, feathery, rich green foliage that holds its color in winter. The leaves emit a pungent odor when bruised. The small tan female cones are not ornamentally significant.

Arborvitae performs best in full to part sun and acidic to neutral soil with average drainage. It appreciates some protection from winter sun and wind, which can cause leaf scorch. It may also need protection from heavy snow and browsing deer. Extremely cold-hardy and highly versatile, this cultivar is an excellent choice for foundation plantings, mixed borders, and hedges.
