Milium effusum is widespread in temperate to subarctic regions in the Northern Hemisphere. North American plants belong to M. effusum var. cisatlanticum Fernald, an elegant native grass that grows in woodlands in eastern North America. It differs from M. effusum L. var. effusum, which grows from Europe to Asia and Japan, in having 2-3 panicle branches at most nodes and spikelets 2.5-5 mm long, rather than 4-5 panicle branches at most nodes and spikelets about 3 mm long. A cultivar of M. effusum, 'Aureum', is grown for its yellowish leaves.
