MAINTENANCE NEEDS: Low Maintenance. Can be an aggressive self-seeder- deadhead in spring to encourage extended bloom and prevent spreading. Crown rot may occur in moist, poorly-drained soils. Foliage decline may occur in hot summers if the soil is allowed to dry out. Snails and slugs can be a problem.
LANDSCAPE USES: Great for borders, containers, and cutting gardens.
