Easily grown in dry to medium moisture, well-drained soils in full sun. Tolerant of heat, humidity and some drought. Plants may be sheared in mid to late summer to promote a fall rebloom and to remove any sprawling or unkempt foliage. Plants will spread by rhizomes. Clumps may be divided in spring. When grown in borders or other formal garden areas, division may be needed every 2-3 years to maintain robustness.
