Cup Plant

Mid-summer is peak time for prairie flowers and Cup Plant (Silphium perfoliatum) is one of the most impressive. Clusters of large yellow flowers top stems that can be over 6 feet tall. The height and its unusual leaves distinguish it from other tallgrass wildflowers. The opposite leaves meet at the stem, forming a cup. This morning there was enough dew to fill it.
