Arrenatherum E. B. 'Variegatum'

Tall Oatgrass, Variegated Tall Oatgrass

Arrhenatherum elatius subsp. bulbosum ‘Variegatum’ is a cool-season ornamental grass valued for its fine texture and bright variegated foliage. Narrow green leaves striped with creamy-white emerge early in spring, form a soft, mounded clump, and may develop light tan tones in summer, with airy, inconspicuous flower spikes appearing in late spring to early summer. Its delicate appearance and early growth make it useful for adding contrast and brightness to borders.
