Letter: Native sunflowers?

To the editor:

After driving on K-10 last week and seeing very, very few native sunflowers, I was heartened yesterday to see a few patches on U.S. 59 south toward I-35, especially in the fields away from the highway’s edge. Then on I-35 South there were some sunflowers blossoming along the overpasses and bridges and a few big patches at exit 183 and 141. But compared to years past, the sunflower show was meager.

Where have all the native sunflowers gone? Is it KDOT’s mowing, especially at seed-setting time? Is it Roundup poison? Does anyone know, because the abundance of our sunflowers in September used to be one of the glories of eastern Kansas.
