Noteworthy Characteristics

Spodiopogon sibiricus, commonly called frost grass, has a bamboo-like quality. The foliage creates bold architectural patterns, and displays purplish or wine tints late in the season. The flowers are 3 to 4" wide, 8 to 12" long and rise 14 to 18" above the foliage, giving a very airy quality.

Specific epithet means of Siberia.


Frost grass grows slowly and poorly in hot climates. It needs to be planted in the "right" spot.


The flowers and foliage provide accents whether frost grass is planted alone or in groups. It is good in small gardens and perennial borders.
