Description
Appearance: Kerria grows 1–3 meters in height, with green shoots that often hang down or cling to other plants. The leaves are lanceolate, with serrated edges, and turn bright yellow in autumn.
Flowers: Golden yellow, can be single or double, solitary or clustered. Flowers are approximately 3–4.5 cm in diameter.
Fruit: In temperate climates, fruits are usually not formed, but in southern regions, small dark drupes appear.
Care and Cultivation
Location: Prefers sunny or semi-shaded locations, but requires protection from cold winds.
Soil: Requires rich, moist soil.
Pruning: To stimulate growth and abundant flowering, pruning after flowering is recommended, removing old shoots.
Overwintering: In harsh winters, shoots can freeze, so shelter and protection from wind are necessary.
Use
Kerria is widely used in landscape design due to its low maintenance, early flowering, and tolerance to urban conditions.
It is planted singly or in groups, and is used to create hedges and line garden paths.
