Calamagrostis foliosa

Southern California growing guide

• Light: Sun near the coast; provide some shade in warmer inland gardens.
• Mature size: Approximately 1–2 feet tall and wide.
• Water & drought: Occasional to moderate irrigation in cool coastal sites. Inland heat calls for more water and shade; avoid treating it as a desert grass.
• Soil: Good drainage is important. Avoid persistently saturated roots.
• Growth: Evergreen, cool-season bunchgrass, producing a low mound and spring flowering stems. Growth and longevity depend on heat and moisture.
• Habitat: Adds grass cover and seed-bearing stems; its wind-pollinated flowers do not offer floral nectar.
• Maintenance: Remove tired leaves and spent stems selectively. Divide or replace aging clumps if their appearance declines.
• Landscape uses: Coastal borders, meadow mixes, rock gardens, woodland edges and small groupings. Tolerates coastal wind and salt spray.
