  • Description

  • Notes

This hybrid CA native is found in wet and marshy areas. It grows to 2'-3' tall with long, thin, graceful, arching foliage. This evergreen perennial has light brown flowers blooming in spring through fall. The flowers are considered insignificant. It can tolerate full sun to light shade.It can become drought tolerant once it's established. Blue gray foliage is very attractive; birds love this plant too.
Dig hole, insert plant slightly higher than soil grade. Disturb root ball very little. No amendments, just native soil. No fertilizers. Backfill the hole .Water lavishly. Mulch top of soil around plant in a 4' diameter circle. - Bert Wilson Las Pilitas
