What’s with all the Yellow Flowers in the Fields
Aaron Hager, Weed Scientist - University of Illinois

If you’ve been driving around a good part of the nation you’ll have noticed a lot of yellow flowers in the fields. Todd Gleason has more on this springtime show.

You’ll see the bright color in fields stretching from Texas east to Florida, northward along the Atlantic coast to Virginia, and back west to Nebraska. It’s butterweed says University of Illinois Weed Scientist Aaron Hager.

Hager :14 …these very bright showy yellow flowers.

Quote Summary - And butterweed is typically a species that germinates in the fall. It will overwinter as a small rosette of leaves and then about late April to the early part of May it bolts and produces these very bright showy yellow flowers.

The bad news for farmers is that because the plant has flowered it is going to get much harder to control.

Hager :37 …made during the rosette stage or early growth stages.

Quote Summary - So, when you see the flowers of these winter annual species, that typically means these plants are nearing the completion of their life cycle. So, we see the bright yellow flowers now, but in a few weeks those flowers would be replaced with a white tuft of seed at the top of the plant. Many times on the larger plant, simply because of how large they are and how close they are to completing their lifecycle, some of the burn down herbicides can tend to struggle as compared with the level of control we would see when these applications are made during the rosette stage or early growth stages.

No doubt farmers will find a way, they always seem to, to control these yellow beauties. In the meantime you might take a ride and enjoy the show.
