We love Gaillardia and so do the butterflies! This nativar grows as an annual for us. Each year we grow a little patch of Gaillardia for the butterflies and for the eye-catching red-yellow flowers.
While it is not the straight species, we think this nativar merits a space in our habitat. It can be planted in small spaces where height and width are a factor. It does well in pots, too.
If I remember I use an organic fertilizer such as Flower-tone but these flowers do fine without it.
