  • Question

    Hi, Here are some photos of a plant growing next to my house. They are in rocky soil next to a stone foundation. The pictures were taken this week. Can you identify the plant? Is it hawkweed? Thanks!

    Answer

    Dear Brookline Biker, the plant you have photographed looks like Lactuca serriola (prickly lettuce). The line of rigid bristles up the midvein of the leaf (underside) is diagnostic. You have also photographed Alliaria petiolate (garlic-mustard), the one with small, white, four-petaled flowers. Best wishes.
