Sedges
From GreenWiki
Sedges are plants very much like a grass or rush.
There are many different types, all beautiful in their own way. It's worth a look at these wonderful photos.
We collect the seeds of the native sedges and distribute or propagate them to create more native gardens.
There's a fabulous Field guide to Sedges of the Chicago Region on the Field Museum website. Special thanks to Sharon for sharing this resource with us!
Sedges which are on the riverbank:(click to see the photos's we've taken) Carex Squarrosa, Carex davisii, Carex pensylvanica (Pen sedge), Carex grayi, Carex sprengelii, Carex granularis, Carex cephalophora, C. vulpinoidea, Carex aurea(golden sedge), C. radiata, and Carex rosea. (an incomplete list.. we'll ask Pete about it later)
The term sedge may sometimes refer to any member of the sedge family, but it often refers only to the genus Carex. Carex is a genus of plants in the family Cyperaceae. The most distinctive feature which distinguishes members of the sedge family from grasses or rushes is that members of the sedge family have triangular stems (with occasional exceptions).
