The plant has silvery foliage. A site with a sunny exposure and any well-drained soil is suitable. The plant can be used on dry, sunny banks or other hot, dry areas. The white flowers are borne in mid-summer. Trim the plants back after they flower and expect some dieback during hot summer weather.
Propagation is by division, seed, or cuttings.
Division every 2 years may be needed to keep it under control. Sow seed outdoors up to 2 months before frost. Plants are spaced 4 to 6 inches apart. Cuttings can be taken in late spring. This information is for educational purposes only.
