Plant Care

This mistflower prefers hot dry locations. It likes gravelly calcareous soil. Plant it in full sun to part shade. Gregg’s Mistflower spreads by rhizomes (underground stems) and recovers readily from pruning or dieback. The rhizomes are shallow, and the plant is not considered invasive, however dividing every two years is recommended to keep the plant contained.

Alternatively, collect seeds in fall and germinate them indoors for planting when soil temperature is above 68 degrees Fahrenheit.
