Blue oat grass. This clumping, evergreen grass grows 2-3’ tall with an equal spread and bears rich blue-silver foliage that delights the eye throughout the year. In spring slender flowering stalks arise bearing delicate nodding flowers that age to a warm wheat color by mid-summer. Though it seldom blooms in mild climates, blue oat grass is a favorite of many gardeners for the foliage alone. Useful as an accent plant in containers, borders, rock gardens, coastal gardens, or even on slopes, this is a plant that performs well in a myriad of settings. Plantings here on the Central Coast have done best with partial shade and moderate water. Hardy to below 0F. Eurasia.
