Question 14

Answer 14

Common Chickweed (A)

Stellaria media
To me, there are two great identification features for chickweed. One is the single line of hair on the stems. It looks like a mohawk or a mullet and it changes direction as the stems come to a joint. The best way to see this is you pick up a branch of chickweed and slowly roll it in your fingers, and there it is, on one side only of the stem, as if the plant was having a bad hair day. I call it a crest.You see, if it has a crest, then it is chickweed. Another peculiar feature of chickweed is inside the stems. If you gently break and pull apart the stem you will notice a core, like a string inside the branch. Chickweed has bones. So here’s the story:it is only chickweed if it shows a chicken crest and if you find a chicken bone.
