Chasmanthium latifolium (River Oats)

A Graceful Native Grass for Shade and Year-Round Interest

Add movement, texture, and four-season beauty to your landscape with Chasmanthium latifolium. This distinctive native ornamental grass is prized for its bamboo-like foliage and dangling seed heads that provide interest from summer through winter.

• Distinctive Seed Heads: Flat, oat-like seed clusters emerge green in summer before maturing to bronze and copper tones in fall.
• Graceful Foliage: Arching, bright green leaves create a lush texture and turn attractive shades of yellow and bronze in autumn.
• Shade-Tolerant Native: Performs beautifully in partial shade and can tolerate deeper shade, making it an excellent alternative to many sun-loving ornamental grasses.
• Clumping & Naturalizing: Grows approximately 2–4 feet tall and gradually forms colonies, making it ideal for mass plantings and woodland settings.
• Adaptable & Hardy: Thrives in moist, well-drained soils but tolerates average conditions once established. Hardy in USDA Zones 3–8.
• Wildlife-Friendly: Seeds provide food for birds and other wildlife, while dense foliage offers valuable cover.

Perfect for woodland gardens, shaded borders, streambanks, and naturalized landscapes, Chasmanthium latifolium provides beautiful texture, movement, and seasonal interest throughout much of the year.
