Chickweed (Stellaria media) is a common cool-weather “weed” that grows abundantly throughout North America and other temperate regions around the world. It also happens to be edible, nutritious, and have a long history of medicinal use.
Chickweed is not native to the US. Rather, it was brought over by European immigrants, but can now be found in all 50 US states.
The extent of its geographic distribution gives you a sense of just how robust and hardy this little plant is!
