Good morning, My wife and I are trying to identify some plants that are on our property. We would love your help. This first plant keeps coming up in our vegetable garden each year since we moved in. We enjoy them so I let a few mature each year. They grow to at least 4 feet and once the frost hits they are done. I thought they would keep their colour throughout the winter but they turn very pale. Thanks for your input. Hal Ottawa, ON
