Plantaginaceae (Note: This is a monocot-like herbaceous perennial, not a member of Poaceae/true grasses)
Grass Category
Invasive/Weed Grass, Pasture/Forage, Medicinal Herb
Variety / Cultivar
Wild type (Commonly 'Tonic' or 'Ceres' when used in forage)
Hardiness Zones
USDA Zones 3-10; high cold and heat tolerance; remains green in mild winters, goes dormant in extreme cold.
About This Grass
Forms a basal rosette of narrow, ribbed leaves. Produces leafless stalks (scapes) topped with dense, brownish, cylindrical flower spikes containing tiny white stamens.
Blade Characteristics
Lance-shaped blades, 2-10 cm wide, 10-25 cm long, dark green, 3-5 prominent parallel veins, pointed tips, hairless to slightly pubescent, no ligule or auricles.
Root System
Deep, thick, branched taproot with fibrous lateral roots; highly resistant to compaction and drought; no thatch formation.
Growing Information
Origin Region
Native to Eurasia; naturalized globally in temperate regions and North America
Growth Habit
Bunch-type, rosette-forming perennial with a deep taproot
Sunlight & Water Needs
Full sun to partial shade; extremely drought tolerant; thrives in poor, compacted, or gravelly soils with pH 5.0-8.0.
Mowing & Maintenance
Maintenance level Low; survives mowing by remaining flat in rosette form; flower stalks emerge quickly after cutting; no fertilization required.
Special Characteristics
Extremely high wear/traffic tolerance; resistant to most common turf diseases; excellent salt tolerance; used in pastures to improve mineral content for livestock.
Ecological Information
Introduced/Naturalized; provides seed for ground-feeding birds; larval host for Buckeye butterflies; indicates soil compaction; often considered a weed in manicured lawns.
