Easily grown in average, dry to medium moisture, well-drained soils in full sun. Established plants tolerate heat and humidity. Plants also tolerate drought, but best performance generally occurs in soils that are given consistent and regular moisture throughout the growing season. Plants grown in dry soils tend to be shorter, open and somewhat spindly. Avoid poorly-drained heavy clay soils. Prompt deadheading of spent flower stalks may encourage additional bloom.
