Vincentoxicum japonicum / Iyokazura イヨカズラ

Vincentoxicum japonicum is a perennial herb inhabiting grasslands or tussocks close to seashores, stems growing erect to 30-80 cm in height; however, the stem tips can reach out like a climber. Leaves are of opposite phyllotaxis, in the shape of an oblong, 3-10cm in length, 3-7cm in width, and have short hairs on veins on both sides. Leaf axils on the upper parts set many light yellow-white, approximately 8mm-in-diameter flowers. Coronas are erect, almost the exact height as columns in size. Follicles are broadly oblong, 4-6cm. Bloom time: May-July.
