FERTILIZING Sparingly use a general purpose 10-10-10 once every 2 months from Spring to Summer for faster growth. Alternatively, use a slow-release fertilizer 3 times a year. Halt fertilizing from the Fall to Winter, then begin again in the Spring. Do not allow fertilizer to clump, be sure to disperse evenly. Clumped fertilizer can potentially burn roots, potentially harming or killing a plant. Avoid getting fertilizer stuck in the crown and sprinkle around the base of the grass instead. Do not over-fertilize.

COMMENTS This low maintenance wetland grass has attractive, tall, unique spiraling reeds. Ideal companion planted along ponds, swampy areas, in water gardens, or containers. The twisted stems are perfect for floral arrangements. Moderate growth rate, we do not suggest pruning this plant. Clumping, spreading slowly by creeping rhizomes. Resistant to insects, deer, and heat. Birds enjoy the seeds in the Fall. Frost will kill the foliage, though new growth will slowly reemerge when the weather warms. In locations susceptible to cold damage, cover with a frost cloth and secure firmly to protect the day before a freeze. Remove promptly once the freeze has subsided. Protect the roots by mulching (with mulch, leaves, hay, etc.) no less than 3″ thick and 1′ radius around the base of the grass above where the roots grow. Native to North America.
