Spodiopogon sibiricus

Common Name: Frost Grass, Siberian Graybeard, Ornamental Grass

Useful for adding a tropical look and feel to northern gardens, this grass looks a little bit like a short bamboo. Bright green leaves measuring .5 to 1 inch wide are held nearly horizontally on upright stems.

Beginning in mid to late summer, erect flower scapes carry 8-12 inch long, deep purple, airy panicles which age to tan. They persist into winter if left standing. In the fall, this grass may turn a rich burgundy red color if sited properly in full sun.

This grass is effective when planted singly or in large drifts in the landscape. It is durable and long-lived.

This grass forms a neat, rounded clump when grown in full sun and moist, fertile soil. It will also tolerate deciduous shade, but the habit will be looser and it will flop if the shade is too heavy. This is especially important in northern climates. In the south, this grass requires partial shade and more moisture than when grown in the north. It resents hot, dry sites and generally grows better in cooler climates. Coastal conditions are tolerated as long as enough moisture is provided. Propagate by seed or division in spring.
