Plant Expert Reply:

What you have is called Spring Vetch (Vicia sativa). In most places it is considered a weed. To get rid of it in your yard, you can spray 2 4 D or a Greenlight product called wipe-out. These products will kill the broadleaf weeds in your yard, but they will not harm the grass.  Your local garden center and nursery in will have this product on the shelf. They will be able to tell you how to mix it and when to spray it in your area.

Caution: 2 4 d or wipe out can only be used in yards. It can not be used in shrub beds.
