Commelina communis is an annual herb commonly seen on
roadsides or grasslands. The lower parts of stems crawl on the
ground and branch well to take roots at nodes to propagate
themselves, and the upper claims arise obliquely upward to 30-50cm
in height. Of alternate phyllotaxis, leaves are ovate-like
lanceolate, with bases becoming membranous sheaths and embracing the
stems. Flowers singly appear from inside inflorescences enveloped in
folded boat-like sheathes that oppositely emerge against leaves and
shrivel in half a day. Two petals are significant: conspicuous,
vivid blue, white, and trim. Bloom time: June-September. |
