|What is a purple queen plant (perennial?)|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
I think you are referring to the plant known also as Purple Heart. Here is a web site with a photo. It is a good tough perennial for sun or shade.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
