Spring and the Virginia Creeper is growing.
https://en.wikipedia.org/wiki/Parthenocissus_quinquefolia
It is native to North America, and common. I read on Wikipedia the berries have "dangerous amounts of oxalic acid" and I have not tried those. The leaves taste good to me; sour and much like sorrel.
I wonder if anyone knows if historically, anyone ate this stuff. Rhubarb has oxalic acid but is good if cooked a little, and cooking is recommended for old sorrel. One would think that back in the days that people ate pokeweed someone would have tried creeper; it is everywhere. But my googlefu is pretty strong these days and I have turned up nothing.
