White Sweetclover is an annual legume originating from Eurasia. Its high seed production and drought-resistance have allowed it to overtake large swaths of land, including many shorelines. ID this invasive by its pea-like white flowers and slightly serrate triplet leaves. 

To remove White Sweetclover, be sure to pull up as much of the deep root system as possible. Pulling before they flower in late Spring will help limit spread.
