Adaptable to loamy, clay, and sandy soils in full to partial sun, it self-sows to slowly form stunning colonies and is naturally resistant to deer and rabbits. Though short-lived, it reliably replaces itself with new seedlings, making it a low-maintenance and long-term presence in moist to medium garden settings.
