Freestone Peach
Frost Grass is a striking ornamental grass with a distinctive bamboo-like quality that brings architectural presence to any garden. This Siberian native, Spodiopogon sibiricus, grows 3 to 5 feet tall and produces showy flowers from July through February that rise airy and ethereal above bold foliage. Hardy in zones 5, 9, it thrives in full sun to partial shade with moderate water and tolerates the challenging conditions of urban settings and maritime climates. What truly sets Frost Grass apart is its seasonal color show: late in the season, the foliage develops striking purplish or wine-colored tints, creating a dramatic transformation that extends the garden's visual interest well into winter.

Frost Grass earns its name through a stunning late-season palette shift, with foliage taking on rich purplish and wine tones as temperatures cool. The flowers are exceptionally airy, reaching 8 to 12 inches long and rising 14 to 18 inches above the plant on delicate stems, creating a weightless quality that catches light beautifully. Its bamboo-like habit gives it bold architectural presence, making it far more than a typical ornamental grass. The blooms dry beautifully, extending their visual appeal long into the dormant season, and this variety's tolerance for urban grit and salt-laden maritime air makes it genuinely tough where others struggle.
Frost Grass is primarily valued as an ornamental grass for creating dramatic architectural structure in garden beds and borders. Its showy flowers make it excellent for dried arrangements and late-season floral displays, bringing interest to the garden when most plants have faded. The combination of bold foliage form and extended bloom season makes it particularly valuable for gardeners seeking year-round visual impact, especially in cooler regions and maritime landscapes where its salt and wind tolerance shine.
