COMMON or SOWN VETCH
There are at least three weedy vetches: the common (or sown), the hairy and the spurred. All are weak annual herbs, with long twining stems. This particular one, sown vetch, can be identified by several leaf characteristics. Firstly, leaves are paired and opposite each other on the stems. Secondly, each of the leaves has a broad flattish top, with a point at the centre top. This can be seen clearly in the second photo above. Also, the leaves are hairy, front and back, also clearly visible in the second photo! The springtime flowers look like those on a sweet pea, but occur singly or in pairs at a leaf junction, and not on a long stem like the sweet pea. These flowers are purply-red to purple in colour. The seedpods also look like those on sweet peas, etc… long straight pods that go brown on ripening. The picture above on the left shows that multiple pods on a stem are common. Originally a fodder plant, this is now a weed over south-east SA.
