I was stopped at the westbound I-70 exit of Kingshighway (in St. Louis, Mo) and I noticed these wild morning glories growing from the crack of the sidewalk. These wild flowers, sometimes called hedge bindweed, tend to be white or white and pink (like these). The flower is near the ground and doesn't grow tall but it is viney so it spreads across lawns easily. Here in the city, I often find them growing out of concrete or asphalt and near buildings.
This patch of wild morning glories was thriving in the urban area.
This is a close up of the flower. This one was growing on the lawn of Forest Park.
Have you ever noticed this flower before in your neighborhood?
