Phragmites australis

Common Name: American Common Grass

American Common Reed is a tall, robust perennial grass that can grow between 3 and 7 feet in height, forming dense colonies in wetlands, marshes, and along shorelines. It provides important habitat and erosion control but can become highly aggressive in some areas and should be used with caution. There are two subspecies of Phragmites australis: subsp. Americanus and subsp. Australis, subsp. Americanus being the Minnesota native subspecies. Subspecies australis (European Common Reed) is considered highly invasive by the Minnesota DNR and should be eradicated. American Common Reed is beneficial for stabilizing wetland ecosystems and supporting wildlife. It can be used in wetland restoration and erosion control projects.

Sowing Information

For most homeowners, the recommended method is to hand-broadcast seed at a minimum rate of 16–64 PLS (Pure Live Seed) ounces per acre. To ensure even coverage, broadcast the seed in perpendicular passes across the site. Grass seed should be broadcast first and lightly raked into the soil. Afterward, apply a light mulch layer using clean, seed-free straw or, preferably, our native Little Bluestem straw, available at our retail garden centers. Once mulching is complete, broadcast native wildflower seed over the area without raking it in. A good rainfall or thorough watering will provide sufficient soil contact for successful germination.

Planting Information

Dig a hole in your planting site slightly larger than the plant’s root system. When placing the plant into the hole, ensure that the soil line remains consistent with its original level in the pot. Fill in around the roots with the excavated soil, gently firming it to eliminate air pockets. Water the plant thoroughly the same day to promote successful establishment.
