In Missouri, we have a weed that grows with small white flowers. The flowers are about 1" diameter and are funnel shaped. I don't have a camera to get a pic, but was hoping someone could help me get a name to look up. I tried googling wildflower small white flower funnel trumpet, but nothing came up looking like my weed.
The funnel of the flower appears to be ONE SINGLE PETAL. Hopefully that will help narrow down the options, as most that I looked up had multiple petals.
