White Sweetclover / Melilotus alba

White Sweetclover (Melilotus alba) was introduced from Europe as a forage crop. It grows along roadsides, waste areas and reclamation sites. Stems can be up to 2.5 m tall and the flower cluster at the top of the stem contains 40-80 tiny (4-6 mm long) white flowers. This cultivated and naturalized plant occurs as a weed across most of Canada. Photographed at Clearwater Park a couple of days ago.
