Full sun and lean, well-drained ground. Because it is a seed strain, plant several to get the full color range rather than expecting it from one plant. Space about 15 inches apart. Colors are strongest in the first flush and soften as the season goes on.

Maintenance
Shear spent flowers to keep it going and to control seeding. Volunteers drift back toward less distinct colors over a few generations, so pull the ones you do not want. Cut back hard in fall rather than leaving stems standing, following the yarrow exception. Divide every three or four years.
