Chamaecyparis obtusa 'Kosteri'

Phonetic Spelling
kam-ay-SIP-a-ris ob-TOO-sa
Description

'Kosteri' is a dwarf cultivar of evergreen Hinoki cypress in the family Cupressaceae (cypress). The Latin name comes from the Greek word chamai, meaning “on the earth,” or dwarf, and kyparissos for “cypress.” The cultivar is named for the nursery (Koster & Son) where it was first seen, in the Netherlands.

‘Kosteri’ is a dwarf, loosely pyramidal form that matures slowly growing 2 to 4 feet tall and wide. This cultivar prefers moist but well-drained soil in full to part sun and has moderate drought tolerance once established. It remains compact without pruning. The ascending branches are large, with bright green, horizontal fans of lush, dense foliage.   'Kosteri' is resistant to browsing by deer.

Use as a specimen in small spaces, in a container, or in rock gardens.  Mass planted it can be pruned into a small hedge or planted along a foundation. The foliage becomes an attractive bronze color, providing winter interest in the landscape.


Insects, Diseases, or Other Plant Problems: Somewhat susceptible to juniper blight, root rot, and insect pests such as bagworms.
