Where are all the wildflowers!?

I always love a walk in the woods in May, when the trilliums, violets, spring beauty, and other wildflowers are in bloom. So when May arrived, after the bloodroot bloomed, I started walking the farther corners of Hanlon Creek to watch for wildflowers in the deciduous woods.

I was surprised to find virtually none. Although there were plentiful leeks in the northeast woods, I found no other flowers. And in the southwest I found only May apple - nice to see, but not as nice as a woods carpeted with trilliums. In fact, the southwest woods was carpeted with a green woodland sedge, a plant that looks like a short grass in the forest.

I can only speculate that past grazing has eliminated the wildflowers in Hanlon Creek, and left us with a nice woods to walk through, but one that doesn't have the normal diversity of native species.
