About this plant
White Cloud Muhly Grass is a warm-season perennial grass prized for its signature white, airy bloom plumes that appear each fall. This ornamental grass thrives in full sun and brings texture and movement to borders, mass plantings, and xeriscape gardens. Once established, it's drought tolerant and requires minimal maintenance, making it ideal for both naturalistic and designed landscapes.
Each plant arrives in a nursery container, ready to plant into garden soil or a larger pot. Plant on arrival or within a few days in a spot with full sun and well-drained soil. Water regularly for the first few weeks while the root system establishes. Expect steady growth through spring and summer, with white bloom plumes appearing in fall.

Questions before you buy
Which size should I choose?
Quart-size plants are perfect for containers or as budget-friendly starters; they'll reach mature size within 2-3 years. The 2-gallon and 3-gallon sizes provide more immediate fullness and impact in landscape beds. All sizes often bloom in their first fall after spring planting.
When should I plant this after it arrives?
Plant as soon as possible after arrival or within a few days. Choose a spot with full sun and well-drained soil. Water immediately after planting and maintain regular moisture for the first few weeks while the root system establishes.
How large does White Cloud Muhly Grass get?
The foliage clump typically reaches 2-3 feet tall and 2-4 feet wide. With fall bloom plumes, the total height reaches 3-4 feet. It grows at a moderate rate of roughly 1-2 feet per year, reaching full mature size within 2-3 seasons.
How much sun does it need?
White Cloud Muhly Grass performs best in full sun, which encourages the densest foliage and most prolific white blooms. It tolerates light or part shade, though flowering will be reduced in shadier locations.
What USDA zones does this grass grow in?
White Cloud Muhly Grass thrives in zones 6-9, with zone 5 possible in some regions. Provide full sun and well-drained soil regardless of zone.
What care does this need in its first year?
Water regularly for the first 2-3 weeks while roots establish, then gradually reduce frequency as the plant becomes drought tolerant. Fertilizer is typically not necessary if the soil is reasonably fertile. Leave the foliage uncut through fall, since the dried plumes provide winter interest, and cut it back to a few inches above the ground in late winter before new growth starts.
