Stellaria Media (Chickweed) Don't be too quick in wanting it gone
I've done a search, and have found post after post asking how to rid oneself of this wildflower.
Thought I might post some information that may change your mind about doing that.
"Chickweed is a very palatable plant & packed with nutrients including Vitamins B1, B2, B3, C & E, Calcium, essential fatty acids, iron, magnesium, manganese, phosphorus, potassium, selenium, silicon, sulfur, & zinc. You can eat it right there on the spot, or add it to your sandwich as a sprout replacement, or add it to your evening salad (Just make sure the area has not been sprayed with pesticides.)"
"MMMM. I love little chickweed! It seems to grow all the time, even in the snow. What a refreshing burst of green it gives you in the winter when nothing else seems fresh! A squeeze of lemon juice, some olive oil, and a little goat cheese and MMM. I adapted a recipe from Tosca's website where I warm an apple or pear in the oven sprinkled with goat cheese. I lay the chickweed down in a plate and hit it with some fresh lemon juice. I put the warmed pear and cheese mixture on the chickweed and finish it off with a sweet vinagrette, such as raspberry or a simple vinagrette made with wine vinegar, honey, and olive oil. A sprinkle of pomegranate seeds makes a nice garnish."
