Easily grown in dry to medium moisture, well-drained soil in full sun. Thrives in poor, sandy or rocky soils with good drainage. Plants grown in dry soils tend to be shorter, open and somewhat spindly. Plants grown in medium moisture soils with consistent moisture tend to be taller and fuller. Tolerant of heat, humidity and drought. Prompt deadheading of spent flowers may encourage additional bloom and prevents any unwanted self-seeding. Freely self-seeds, and in optimum growing conditions will naturalize to form large colonies. If grown in borders, division may be needed every 2-3 years to maintain robustness.
