Creeping Wild Rye — Leymus triticoides

Leymus triticoides (also known as Elymus triticoides)

A spreading California native grass for broad meadows, seasonally moist ground and habitat restoration. Underground rhizomes build a dense network that helps hold soil.

Growing profile

• Light: Full sun to light shade.
• Water: Establish with regular irrigation. Adaptable to seasonal moisture; tolerates some drought in heavier soils, though foliage may look drier.
• Mature size: Usually 2–4 feet tall; colonies spread 4–6 feet or more and continue expanding.
• Soil: Adaptable to clay and other soils, including seasonally moist sites.
• Growth: Establishment can be slow; established rhizomes spread vigorously where moisture is available.
• Wildlife: Supports grass skipper butterfly larvae and provides nesting material for birds. Wind-pollinated rather than a showy nectar plant.
• Care: Remove dry foliage as needed, cut back before fresh seasonal growth and control spreading edges.
• Uses: Large native meadows, restoration areas, drainage landscapes and soil stabilization planting.

Allow room to spread: This is generally unsuitable for small mixed borders where it can overrun neighboring plants.
