Sisyrinchium atlanticum / Niwazekishou ニワゼキショウ

Sisyrinchium atlanticum, a perennial herb originating in North America, is broadly naturalized in various places like sunny lawns, roadsides, etc., growing to 10-20cm tall. Stems are planes with narrow wings and 2-3mm-wide leaves. Slender peduncles emerge from the stem's ends, and small flowers bloom from one to another. The flowers, about 1.5cm in diameter, wither in a day. Perianth lobes are purple or white-purple, with dark color stripes and yellow in the center parts. Capsules, about 3mm across, are spherical. Bloom time: May-June.
