1. Kerria Japonica

The Kerria Japonica, a deciduous shrub from the Rosaceae family, is characterized by green, angular, hairless branches. Its singular leaves are alternately arranged in ovate or triangular ovate shapes. The plant boasts large, bisexual, hairless-pedicel flowers.

Its petals are yellow, broadly elliptical, and slightly concave at the top. Numerous stamens surround a ring-shaped floral disc.

The column is terminal and upright, leading to an inverted ovoid, laterally compressed, dark brown achene. Its flowering period spans from April to June, while its fruiting period lasts from June to August.

Originally from Northern to Southern China, the Kerria Japonica thrives on hillsides and within shrubs. It is a light-loving species, moderately shade-tolerant, and prefers a warm, humid climate.

Its cold-resistance is relatively weak, but it possesses a strong capacity for tillering. Modes of propagation include seeding, dividing, and cutting.

The Kerria Japonica has a slightly bitter, astringent taste, and neutral properties. It is known for its therapeutic effects—expectorant, antitussive, diuretic, anti-inflammatory, and detoxifying.

It is used to treat coughs, rheumatism, edema, indigestion, eczema, and urticaria. In addition to its medicinal uses, the Kerria Japonica also serves as a beautiful addition to landscapes.

2. Kolkwitzia Amabilis

The Kolkwitzia Amabilis, also known as the Beauty Bush, belongs to the Caprifoliaceae family. It is a deciduous, multi-branched shrub that can grow up to 3 meters high.

The winter buds feature several pairs of soft, hairy scales, with the young branches displaying a reddish-brown color, covered by soft and rough hairs, while older branches are hairless.

The bark of the stem tends to peel off. Its leaves are elliptical or ovate-elliptical, occasionally with shallow teeth, and both surfaces sparsely bear short hairs. The veins and leaf edges are densely covered with straight, soft hairs and eyelashes.

The bracts are lanceolate, closely attached to the base of the flower, and the calyx tube is densely covered with stiff hairs, constricting towards the top into a neck.

The fruit has angular tips and is covered with bristle-like hairs, which earns it the name “Beauty Bush”. It blooms from May to June, and the fruit ripens from August to September.

Native to many regions in China, the Beauty Bush is commonly found growing on mid-altitude slopes, roadside, or in bushes, at elevations from 350 to 1340 meters.
