About Ferner Osten Maiden Grass

Miscanthus sinensis 'Ferner Osten' · also called far east maiden grass, ferner osten miscanthus · flowering

Ferner Osten is a compact maiden grass prized for deep burgundy-red plumes that open in late summer and fade to silvery beige. Narrow arching green blades form a tidy upright clump roughly 1.2-1.5 m tall. It thrives in full sun and average soil, needs little once established, and provides strong autumn and winter structure.

Ideal humidity: Any outdoor humidity

Watch for — Flopping clump: Too much shade or over-rich, over-watered soil makes stems weak and splayed. Site in full sun and withhold heavy feeding.
