Clematis koreana is native to the Korea, north east China and east Siberia. In its native habitat it grows in forest scrub.

The etymological root of the binomial name Clematis is from the Greek klema meaning a ‘vine branch’, alluding to the vine like habit of the climbing members of the genus. Koreana is derived from the Latin meaning ‘from Korea’.

The landscape architect may find  Clematis koreana useful as a climber within a dappled woodland setting. A framework for this plant to cling to is necessary as it is a twining plant. As with most Clematis species this species prefers cool roots.

Ecologically, Clematis koreana flowers are attractive to pollinating insects.

Clematis koreana prefers moist, free draining soils. It tolerates most pH of soil although it prefers a slightly acidic pH. It dislikes wet soils.

Clematis koreana requires little maintenance. If required pruning may be carried out after flowering.
