Birdfoot Trefoil (Lotus corniculatus)

Lotus corniculatusPhotographed June 13.

This is a plant that seems to be adapted above all to roadsides. It thrives in poor soil and can live happily in gravel, and it stays short enough to laugh at occasional mowing, though it would not survive a mower-obsessed suburbanite’s lawn. It is certainly one of our most decorative roadside weeds. The bright yellow flowers reward a close look: they have thin red stripes on the “standards,” the upper part of the flower.
