Like many recent posts, Climbing False Buckwheat has made a previous appearance. It's probably one of the few remaining species holding some late color.
The Wayside Flowers of Summer:
"A conspicuous weed climbing that has found the modern wire fence admirably adapted to its needs and shares it with the Wild Morning-Glory. It is, moreover, capable of shouldering its way through the bushes of a thicket and displaying its flowering racemes in profusion in the sunlight at the top. When no other support offers, it spreads itself over a square rod or so of ground and holds up its fruiting racemes to light and air. It is a capable, efficient, and successful weed. The leaves are usually halberd-shaped, the points of base and apex making an attractive form; the racemes are rather more conspicuous in fruit than in flower, and the bright, shining, Buckwheat-like seeds are full of food for the birds. They remain on the stems until cold weather comes or the birds remove them."
