The orchard here is near and home-like.
The oats in the valley run a mile.
Between are the green and marching potato vines.
The lightning bugs go criss-cross carrying a zigzag of fire
From "Potato Blossom Songs And Jigs" by Carl Sandburg
Wild Potato Vine has large, striking flowers with a flared trumpet shape, white with a dark pink center. Typical of the Morning Glory family, the flowers are only open during the morning. This plant is plentiful on fence rows and in the ditches alongside the gravel roads around my home.
This plant is reported to have a very large root, sometimes weighing over twenty pounds, but I've never dug one up to see for myself. It is also known as Manroot or Man-of-the-earth.
