Small Japanese Silver Grass (Miscanthus oligostachyus)
Description
Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Tolerant of a wide range of soils from well-drained sandy soils to the heavy clays present in much of the St. Louis area. Prefers moist soils. Best in full sun. Less vigorous with decreased flowering and tendency to flop in too much shade. Tolerant of summer heat and humidity. Clumps slowly expand in circumference by short rhizomes, but retain tight clump shape. Foliage should be left standing throughout the winter for visual interest and to provide protection for the crowns. Cut foliage to the ground in late winter just before new shoots appear.Miscanthus oligostachyus, sometimes commonly called small Japanese silver grass, is native to Japan (Islands of Honshu, Shikoku and Kysuhu). It is a compact miscanthus that typically forms an open, upright-arching clump to only 2' tall and as wide of flattened green leaf blades (each to 1/2" wide). It is similar in appearance to Miscanthus sinensis, but much smaller. In August, tiny pinkish-silver flowers bloom in sparsely branched tassel-like inflorescences that rise above the foliage clump to 3-4' tall. Inflorescences turn silvery white by fall as the seeds mature. Leaf blades acquire bronze-red tones in fall before turning beige in winter. This species is noted for having excellent cold hardiness and for tolerating part shade conditions.
