This week's prairie plant is another forb (herbacious flowering plant) that most of us see in proliferation each season; though locally it does seem to have its boom and bust years.  The Evening Primrose, or Common Evening Primrose (Oenothera biennis) is a biennial (note the "biennis" in the latin name), so it takes 2 years to flower.

This plant tends to be grazed on by everything hungry though, and can tend to have some rather ratty looking stands in some years.  We have a large stand of volunteers along side the corn crib that have been skeletonized by this year's crop of grasshoppers!  There are also insects that tend to be found or associated with different plants.  The vertical image below has a couple insects on the top of the plant that can be seen with the Evening Primrose every season.  I'll plead ignorant of the insect's identity and it's association with this plant - something to look into for future reference!

We have this plant on our prairie pasture frequently; most commonly along the gravel hillside and the gravel road going past our place.  It volunteers quite easily and needs no seeding or help from us.  It is really quite striking in large stands...I once found a stand along a railroad bed that was at least a hundred feet long and 12 feet wide - it was amazing!

Some Native American tribes collected it's seed for food and most first nation people used the "first season" roots - gathereed and dried for food.  They were also adopted for food by the Europeans when they arrived.

They are great food plants for the birds and our pollinators  - very important for all of us!

Thanks for stopping by - next time you're out along a gravel road or prairie remnant - look for this beautiful native prairie plant!
