Japan Globeflower (Kerria japonica)

Kerria japonica, commonly known as Japanese kerria or Japanese rose, is a deciduous, yellow-flowering shrub in the rose family (Rosaceae), native to China and Japan. It is the only species in the genus Kerria. In the wild, it grows in thickets on mountain slopes. Japanese kerria has been used for medicine and is also planted in gardens. A double-flowered cultivar, K. japonica 'Pleniflora', is commonly called bachelor's buttons. When cultivated in the Central-Southern U.S., the plant is usually called Yellow Rose of Texas. Although the genus Kerria is in the rose family, it is not a true rose.
