Gray's sedge or burr sedge! Thanks to my readers who helped identify this for me!
Given the information about this sedge, I am surprised to find it growing in my shady forest. It likes wet, but typically it needs more sun than my woods get. But this little patch has been growing back every year, so it must like it here.
Welcome to our garden! Since 2007 we have been striving to turn our lawn into something beautiful, tasty, ecologically sound, and a centerpiece of our community here in Franklin, Massachusetts. We hope you enjoy your visit!
