Convolvulus arvensis is one of the most successful weeds worldwide. That said, its sweet little flowers make it very hard to dislike this plant, even though I spend at least 20 minutes every week weeding it out of my garden. Its flowers come in 2 colors, white or pink (see photos below), which close at night.
C. arvensis is native to Eurasia and is widespread across the US. It is in the Convolvulaceae family and is a perennial.
