Maintenance

This is a low maintenance plant. Spreads quickly by rhizomes, but roots are shallow and is easy to pull out. Tolerates poor drainage. Can grow in full sunlight with extra water, but does better with shade in the late afternoon. Spring: Thin, divide, and transplant. Hand remove weeds and unwanted seedlings. Winter: Prune dead material down to new growth in late February. Propagate by root division.

Comments

Fluffy-edged light blue flowers. Good as a border plant or colonizing by rhizomes to form groundcover. Especially attractive to butterflies, moths and other insects in the Fall.
