The number one reason I like having the Gregg's Mistflowers in my garden is simple. They are the only plants I've seen the adult Queen Butterfly nectaring on when I've spotted them. The Queen is related to the Monarch butterfly but sports a very regal orange brown coloring with black wing borders with white spots. A bit rare in Oklahoma, the Queens I've observed are most likely males that obtain a compound from the Gregg's mistflowers they use to simulate pheromones to attract mates. Gregg's Mistflowers are also drought tolerant, don't spread as mush as common mistflowers and look great in cottage-style gardens. This is the white form with gleaming frothy flower clusters and attractive deeply lobed leaves. It looks great when inter-planted with the blue form.
