Noteworthy Characteristics

Carex frankii grow abundantly in Missouri in wet locations such as swamps, wet meadows, wet prairies and around rivers, lakes, streams and ponds. Its grass-like leaves grow up to 1/3" wide and 2' high. The seeds, which form thin thimble-shaped heads, are eaten by waterfowl.

Genus name from Latin means cutter in reference to the sharp leaves and stem edges (rushes are round but sedges have edges) found on most species' plants.


The foliage may be less attractive in summer, although supplemental watering may help.


This sedge grows best in moist soil such as that around water gardens or along streams. It is also useful for establishing native plants in shaded wooded areas and meadows.
