Origin: Asia

Description

Mile-a-minute is an herbaceous, annual, trailing vine that can reach lengths of 6 m or more. Its stems are covered with barbs, which are also present on the underside of its leaf blades. The light green-colored leaves are triangle-shaped and alternate along the stem. Iridescent blue berry-like fruits are produced in mid-summer and continue until the fall. The seeds within these fruits can remain viable in the soil for up to six years.

Habitat

Mile-a-minute typically colonizes open and disturbed areas such as forested floodplains, stream-side wetlands, upland forests, uncultivated fields and roadsides. Although mile-a-minute will tolerate some shade, it does best in full sunlight.

Threat

Mile-a-minute has gained a reputation as “the kudzu of the north” for its ability to quickly grow over and out-compete native plant species. In ideal growing conditions, a single vine can grow as much as 6″ per day. Because it can smother tree seedlings, mile-a-minute vine can have a negative affect on tree farms, forestry operations, and the reforestation of natural areas.

Management

The most common management methods for mile-a-minute include manual pulling of juvenile plants and selective herbicide treatments. There are also biological control weevils, Rhinoncomimus latipes, that are currently being used for mile-a-minute control.
