I have been trying to ID this plant for years and just found out what it was. I have at least one wild plant growing in the briers, bushes and weeds along the road frontage. The plant is about 8 feet tall and 3 feet wide ! I will definitely be collecting seeds this year to try to grow more in my gardens. It's a beautiful plant, and if the insects and hummers love it, all the better.

Tall to 7' - Plant 24" apart. z5-10. Equally good in the border, and as a candidate for container growing. The better the drainage the happier the plant. Attractive to hummingbirds and butterflies, with mint scented foliage.
