Purple Prairie Clover was in full bloom along the highway on our drive back from Colorado in Nebraska, Iowa and Minnesota. One of my favorite mid-season native perennials, it has bright purple conical shaped blooms with orange stamens that stick out beyond the petals.
Here is a bumble bee about to enjoy the nectar.
We have tried to establish Purple Prairie Clover in our yard for several years, but had it browsed heavily by rabbits. This year though, now that the surrounding plants have filled in it is flowering nicely.
It is native to Alberta southwards to Arizona and east to Ontario in the north and Georgia in the south.
