Iowa Wildflowers

Blue Vervain
(Verbena hastata) |
|
When I see the blue vervain is flowering, I know that the peak of the wildflower season has certainly passed and the transition to autumn has begun. Sure, the days may still be hot, but all I need to do is look around and I will notice that most vegetation is beginning to look tired and aged. The vibrant colors of fall will soon surround us.
