What is this stuff? It grows around a big old tree by my front door. Last year I thought it was a weed and weed-whacked it a bunch of times before I realized that it smells good and the leaves taste good. It tastes like parsley or celery. (Yes, I've still got snow...)
Below is rhubarb, looking like it's getting ready to flower. Should I let it flower, or is it better to get rid of these blossoms-to-be?
