These are classic prairie plants.
Ratibida columnifera f. pulcherrima ‘Red Midget’
I love the dark maroon colour and the simplicity of the flower form. It is very floppy, but not so tall that hard to give it reasonable support. I sowed them from seeds.
I sowed this from seeds to use as a filler many years ago. I still haven’t get around to use it properly. I hate its floppy habit. It is such a tall plant that it is not easy to find a companion to support it.
