This is absolutely the most wonderful native to bloom in our light shade garden in August! When the rest of the flowers are getting a little heat stressed and tired, the bright red blooms are electric.

I bought this plant as a wee baby this past spring and wondered how it would ever survive in my mostly sunny, clay garden. A couple of my wild flower plants did not like it. But this plant seems hardy. It is now August and it has grown to be 2 feet tall and is blooming just as in the picture. The hummingbirds have already visited it several times. I plan to get more next spring.
