Description

This dwarf Acorus, commonly called Sweet Flag, creates a colorful patch or mass planting of bright green and gold foliage in consistently moist to wet soils, making it a perfect choice to fill damp areas where many other plants won’t grow and to fill spaces between stepping stones. That said, it does not like standing water. As with other Acorus, when the leaves are crushed they emit a citrus-like fragrance.

Landscape & Garden Uses

Growing only 3 to 4 inches tall and spreading slowly by rhizomes to 12 inches wide, Dwarf Golden Sweet Flag is a perfect choice for use as a bright groundcover around darker colored shrubs and trees in landscape borders and home foundation plantings where there is consistently damp soil. It can also serve to fill spaces between stepping stones, looks great around rocks and boulders around the garden pond, and is a colorful soil cover in container gardens. Excellent for damp areas in ornamental grass gardens, rock gardens, woodland gardens, and yellow theme gardens.

Suggested Spacing: 8-12 inches apart for mass plantings; 24 inches or more apart for space between plants

Note: For our customers who live and garden north of USDA Plant Hardiness Zone 5a, where this Sweet Flag variety is not reliably winter hardy, you’ll be happy to know it can be grown in containers that can be brought indoors during winter and placed back outside when temperatures warm up in spring.

Growing Preferences

When planted right and in the right spot, Dwarf Golden Sweet Flag is easy to grow. It adapts to most soil types provided they are consistently moist to wet soil. It doesn’t like standing water or the soil to dry out. With moist to wet conditions it will grow in full sun, but appreciates some afternoon shade in hot climates. When growing in part shade it will tolerate dry periods.

I have a rain garden and the dwarf golden sweet flag is perfect as a ground cover. Not only does it thrive the regular flooding and draining, but it also is not affected by the black walnut tree next to the garden. I’ve ordered these from Wilson Brothers several times over the years, and they always arrive healthy and ready to plant.————————————————————–We are so glad you are pleased and we hope you enjoy them for years to come!
