The flowers of Purple Prairie Clover bloom from the bottom of the cone upwards. A wreath-like cluster of flowers can be seen. As the blooming season progresses, the flowers bloom farther up the cone. Though difficult to see, each bloom on the cone of the flower contains tiny pink to purple flowers with 5 petals. Bright orange stamens are present around the cone as well. Where the flowers have not yet bloomed, you can see the green to gray calyx that holds up the flowers that bloom.
