Birdsfoot trefoil is a small, delicate looking yellow wildflower in the pea family. But don’t let it fool you, this little flower is one tough cookie. It has a long bloom period, beginning early summer and extending through the first frost. If it sprouts up on your lawn, good luck getting rid of it. You’d have to destroy the root system. Mowing it down only shortens the height, as birdsfoot will continue to flower. Might we all be so strong as the mighty little trefoil?
