Other info. - This popular cultivated species is found in scattered locations throughout Missouri and the eastern half of the continental U.S. It is easily recognized by its blue flowers, which can be abundant, and creeping habit. The foliage is similar to that of the badly invasive wintercreeper (Euonymus fortunei), but the leaves of that species have blunt teeth along the margins, and the flowers are totally different. V. minor also closely resembles its sibling V. major, but the leaves of that species are larger, with finely hairy margins and more truncate bases. The leaves of V. minor have entire, glabrous margins.
