This is a member of the lovely vining Morning Glory family, opening its blossoms as the morning light highlights its beauty. However, this species is one of those non-native, Eurasian varieties that is a dreaded invasive visitor in American gardens. Known as Field Bindweed (Convolvulus arvensis) I enjoyed taking its portrait during a morning bike ride along a Lake Michigan pathway in Lincoln Park, far from any cultivated gardens. They appeared a fair distance from a prairie restoration area and were isolated from the golf course by a stone wall making their appearance more tolerable to the native purist. This Bind Weed did emulate its name wrapping around other vegetation proliferating this informal, unplanned area of horticulture.
