ARRHENATHERUM elatius var. bulbosum 'Variegatum'
Plant Common Name
Tall Oatgrass, Variegated Tall Oatgrass
This variegated grass spreads quickly by small round corms. Its pretty blades are gray-green with white edges.
Bulbous oatgrass is a perennial grass that is native to Europe. It is considered an invasive weed in many parts of the western United States. It spreads and may escape beyond the confines of a garden, so manage it diligently if you plant it.
This prolific grass has green and white blades that are short, upright, linear and rough to the touch. The inconspicuous pale green flowers are produced in late spring and early summer and resemble oats.
Bulbous oatgrass prefers full sun and moist soil but will grow in drier locations. In the heat of summer it may go dormant but will reappear in fall. Its dry leaves and seed heads are very flammable.
