Since we’ve inherited a yard and garden with lots of these, we’re rethinking what’s a weed. McK likes anything that flowers:

Simply expressed, a weed is any plant that grows where it isn’t wanted. Weeds are defined by their tendency to flourish at the expense of a gardener’s overall vision, and we tend to battle their presence in our yards. It is interesting to consider, though, that a plant is a weed only within a certain context, which is to say that one person’s weed is another person’s wildflower. Most of us have pulled at least one dandelion up by its roots and disposed of it in the interest of preserving the look of a perfect green lawn, yet the dandelion is good medicine, packed with healing properties and vitamin-rich leaves that are a delicious, spicy surprise in a summer salad…

Speaking of, some recipes Dandelion Greens with Sausage sounds good to me.
