These two plants are very common in our area - teasel and thistle. They are found in fields, on the side of the road, in parks with unmowed grassy areas. Teasel is native to Europe and was introduced to the United States in the 1800's. There are native and non-native varieties of thistle. I love the sharp texture and shape of both of them, so different from most flowers. The insects love them also, especially the purple thistle.
Same view, three different images - purple thistle, a common wildflower, teasel.
