Bird's-foot Trefoil is so named because its seed pods are arranged like a bird's foot. It has clusters of 3-8 flowers arranged circularly at the top of the stalk. The flowers are yellow, but often with orange or red streaks.
It was originally grown for fodder, and it can reduce methane emissions from cows. The pasture plant tends to be a larger variety, and is often seen on roadsides.
Bird's-foot Trefoil is similar to Meadow Vetchling, but does not have tendrils.
