(aka Blue Vetch, Tufted Vetch, Bird Vetch)
Cow Vetch is an excellent source of nectar for bees and butterflies. The plant grows to a height of two to three feet with flowers growing in clusters on long stalks.
The flowers range from blue-violet to purple in color and bloom late spring through late summer. In early August the flowers drop off and pea-shaped seed pods form, varying in color from light to dark brown.
Cow Vetch is appreciated for its erosion control and enriching nitrogen-fixing properties and is often used as a forage crop for cattle.
Since it often crowds out native plants it is often considered an invasive weed and may not be available for sale.
