Description of Birdsfoot Trefoil (Lotus corniculatus):
Birdsfoot trefoil grows to a height of 2 - 3 feet, with slender stems that branch and have a medium amount of leafiness. The bloom is a customer of bright yellow flowers that are arranged in a whorl (basically a spiral). It grows well in poorly draining areas and low in pH, therefore correcting these soil conditions may show natural improvement in control.
