lesser celandine and sorrel

Aha--I now know the name of the weed on the right. It's lesser celandine. Thanks, Libbey Oliver! The leaves on the left are sorrel, a gift from Erin Bishop on Easter Sunday. Can't believe how long they have lasted, but Erin "packaged" them perfectly by putting them in this narrow glass with a paper towel around the stems and the towel wicking up water. The leaves are so sour--like a lemon!
