Cultivation and Uses
USDA hardiness zones:
8b-11. This plant dies to the ground in freezes and comes back
from its roots in the spring.
Needs part shade, especially afternoon shade, and extra water, over 90°F.
Full sun to part shade. Avoid full shade.
Water after becoming established: Deep water
every 2-4 weeks, depending on temperature, to establish a deep root system that can withstand
high temperatures and drought.
Very well drained, dry, low in organic content, pH 6.1-7.8 (slightly acidic to
slightly alkaline). This plant is salt tolerant.
First Year Care:
Locate in an area with full afternoon shade in regions with high
temperatures. Water once when planted, then deep water after one week, then every two to four
weeks as needed.
This plant can be grown on a mound for better drainage.
Cut back by one-third in fall or winter to encourage a more rounded, bushy shape,
or clean up after the last freeze of winter. Deadheading spent flowers encourages more blooms
but eliminates seed for birds.
Seed, rootball division.
Butterfly garden, fragrance garden, xeric garden. While edible, the leaves and
flower heads have a slightly bitter taste and are seldom used.
