I live in Iowa, zone 5, and my wife planted what she called a vine in the backyard last year. Photos to follow. It has come back this year, it has four strong stalks that emerge separately from the ground and each main stalk throws out a few lateral runs along the way. While it is placed near a wall, it isnt clinging or climbing. I don't believe it flowered last year, but this is the first full season in our garden, so I make no promises about what tricks it might have, but it doesnt look like it will. We both like this plant a lot and we're finally documenting what we have in a gardening binder.
Any help identifying this fellow is greatly appreciated. My first time to this site... I'm afraid I'm going to be here a lot. Worse addictions, there are. Thanks again.
