The morning glory family (Convolvulacae) contains hundreds of species around the globe, and dozens in the United States. Here it seems most are restricted to the southern part of the country, but several are widely distributed. One of these common species is hedge false bindweed (Calystegia sepium, Convolvulaceae). A few weeks ago I found a number of these plants growing along a sunny trail leading to Rockbridge State Nature Preserve near Logan, Ohio.
Most morning glories are vines with showy flowers, and this bindweed was no exception The big white flowers were maybe 2″ in diameter and at least as long. The stems were twined around other plants, giving the bindweed support while allowing the leaves to reach sunlight.
The leaves themselves were long, narrow, and saggitate (arrowhead-shaped) with rounded lobes. Their unique appearance helps set them apart from other widespread morning glories, including some invasives like field bindweed (Convolvulus arvensis).
