General Description

Leaves with toothed edges visually compliment the many small, nodding yellow flower buds and blossoms of Clematis serratifolia. Native to gravelly soils and slopes of far eastern Siberia, northern Japan and Korea, this woody vine blooms in late summer.

The three leaflets that make up each leaf are lance-shaped, rich green in color, and lines with jagged teeth. In mid- to late summer, many small, nodded and round yellow flower buds appear on slender stems above the foliage. Each opens to reveal four, petal-like sepals that often face downward protecting the purple, red-brown stamen cluster. As the flowers age, they are held outwards, better attracting insects for pollination and resulting in attractive silvery seed heads that look like spidery fireworks.

Grow the Korean clematis in full sun to partial shade in a wide range of coarse to average garden soils, clay to sand, that have some organic matter incorporated. Moreover, the soil should be alkaline to neutral in pH and kept cool and moist with mulch, particularly in regions with hot summers. Prune it back annually in late winter to waist height for best growth and increased flowering. Use it as a trellised vine upon a garden wall or in a large container on the patio or entrance step climbing a porch column where its interesting flowers and seeds can be readily admired. Selection 'Kugotia', the Golden Tiara clematis, has deeper golden yellow flowers.
