Tall Anemone, a.k.a Thimbleweed, Blooming in Pennsylvania

A couple weeks have passed since we first saw this family of ducks. So far, only one of the ducklings has disappeared, but we’re hoping the rest will make it through the summer.

Reading about the varieties of wood sorrel in my field guides I came across a picture of a tall yellow-flowering kind that I had not seen before, so I made a mental note of it. That’s why I was pleasantly surprised to see a Great Wood Sorrel plant on my berry walk this morning down the lane. Growing in the shade next to the lane, this Oxalis grandis specimen is about 16 inches tall.

Small clusters of flowers arise from the leaf axils and the leaves are held out quite straight and horizontally.

With the number of times we’ve walked up and down the lane we don’t expect to find any new plants. We were quite surprised to see this pretty flower – a weed, really, hiding in the shade of the oak trees.

The central leaflet is wedge-shaped and has curved sides, a feature that distinguishes the plant from other anemone species.

This member of the buttercup family, Anemone virginiana, has an interesting fruit which obviously lent the plant its name – Thimbleweed, also known as Tall Anemone.
