Date Location Notes Images
July 13, 2009 Southeastern, New Hampshire This plant appears to be Yellow Wood Sorrel. Low, spreading plant. Yellow flowers. They haven't opened yet, but they should have 5 yellow petals with 10 stamen (when they do open). The leaves are divided into three heart-shaped leaflets that are each 1/2 inch to 3/4 inch wide. The leaves do have a slightly sour and a bit of a lemony flavor.

I will wait for the flower to open for positive identification.
July 17, 2009 Southeastern, New Hampshire Confirmed that this plant is Yellow Wood Sorrel (Oxalis stricta) and not Creeping Woodsorrel (Oxalis corniculata). Both have a 5-petal yellow flower and similar leaves. Some key distinguishing features include:

  • Yellow Wood Sorrel tends to grow more upright, while Creeping Woodsorrel grows very close to the ground.
  • Creeping Woodsorrel can sometimes have purplish leaflets (but not always).
  • Yellow Wood Sorrel roots at the rhizomes (stems spreading below ground) while Creeping Woodsorrel will often root at the nodes. (Leaf stems grow out of the nodes.)
Made an Oxalis-aide using the following ingredients:

  • 1/2 cup of Yellow Wood Sorrel leaves, stems, flowers, seed pods. Washed and chopped.
  • 1 quart of spring water.
  • 1 Tablespoon of agave nectar or honey. May try maple syrup next time.
  • Dash of sea salt.
Mixed all ingredients in a Vitamix (heavy-duty blender) and refrigerated it.
July 18, 2009 Southeastern, New Hampshire Finally saw an open 5-petal yellow flower of the Yellow Wood Sorrel. Pressed the juice out of a couple of small plants. You don't get much! Then I mixed the juice with a touch of flour to thicken and put it on my skin. This is the type of thing that would traditionally be put on skin cancer. See the Yellow Wood Sorrel Identification & Uses web page for more information.
