Cultivation and Uses
USDA hardiness zones: 7b-11, depending on cultivar. This plant dies to the ground
in freezing temperatures and recovers from its roots in the spring.
Heat tolerant: Somewhat. It does poorly in temperatures over 100°F.
Drought tolerant: Yes.
Sun: Full sun in cool months. Up to three-quarters shade in the hottest months of
the year.
Water after becoming established: Once or twice a month in temperatures under
85°F or in part shade, weekly in high temperatures. It is tolerant of frequent
watering if the soil drains quickly, but overly moist soil results in leggy, weak stems.
Some varieties need more water.
Soil: Well drained, dry to slightly moist, low in organic content, pH 6.1-7.8
(slightly acidic to slightly alkaline). This plant is moderately salt tolerant.
Fertilize with compost in March and July.
Mulch: Do not mulch, especially in part shade.
Prune: After extended flowering, prune for more compact growth which will
temporarily reduce flowering. Prune spent flower stalks to promote new flowers.
Litter: Low except for pruning.
Propagation: Seed planted in the fall.
Uses: Ornamental, wildlife attractor.
