Carex comosa, commonly known as Bottlebrush Sedge or Bristly Sedge, is a perennial sedge that typically grows 2 to 4 feet tall. It features narrow, arching leaves and distinctive, bristly seed heads that give it its name. This species is commonly found in swampy or boggy areas, lake and pond shores, and riverbanks across much of Minnesota, often in shallow water and rooted in muck.

Sowing Information
Sow seed onto a firm, weed-free seedbed. Hand-broadcast seed making two perpendicular passes for even coverage. If planting a mix, broadcast the grass component first and lightly rake/drag it into the top 1/8–1/4" of soil. Next, broadcast wildflower/forb seed and press it into the soil surface (with a roller/cultipacker or the back of a rake) to ensure good seed-to-soil contact. After seeding, apply a very light layer of clean, seed-free straw (or other weed-free, site-appropriate mulch) to reduce erosion and retain moisture without smothering seedlings. A good rainfall or thorough watering will help settle seed and mulch and improve 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.
