Sub-category: Plaintain family
A native of Eurasia. First recorded in Britain in 1825 and now widespread in the United States, and east Asia (including Japan). Its cotyledons are triangular with truncated bases. The short-stalked leaves are broadly ovate with coarsely serrated margins, and measure one to two cm long. The leaves are paired on the lower stem and are alternately arranged on the upper parts. The plant has weak stems that form a dense, prostrate groundcover. The tips of stems often grow upright. The flowers are roughly 1 cm wide and are sky-blue with dark stripes and white centers. They are zygomorphic, having only one vertical plane of symmetry. They are solitary on long, slender, hairy stalks in the leaf axils. V. persica can be distinguished from similar species by its heart-shaped fruit with two widely-separated lobes.
Most often seen growing as a weed in lawns and fields.
