Bird's-foot Trefoil / Lotus corniculatus

It's so unfortunate that this beautiful member of the Pea family (Fabaceae) is considered a weed. It is grown as a crop and has spread to various places. Introduced from Eurasia, it can be found (if you know where to look) growing along roadsides and on waste areas. I think I've only ever seen it in about four or five places, though. It blooms from June to September. The plant was named for the arrangement of the long, narrow seedpods/legumes, which resemble a bird's foot. A handful of us had driven past a colourful roadside display two days ago, and I just had to go back yesterday on my way home from Brown-Lowery Provincial Park, to grab a few (macro) photos.
