Missouri Coneflower, Rudbeckia missouriensis
Aster family (Asteraceae)
Missouri coneflower is a Missouri native perennial. You can find these yellow flowers in limestone glades in the Ozarks. I noticed them along roadsides in late June and early July.
Rudbeckia missouriensis can spread to form wild colonies of yellow flowers growing between 2 and 3 feet tall. Daisy-like flowers have yellow rays and black center cones.
Narrow green leaves and the multiple stems are hairy. Long summer to early fall bloom period.
You may have seen yellow coneflowers outside of Missouri. Their growing region stretches into AR, IL, LA, MO, OK, TX.
I saw these yellow conflowers on the road to Laura Ingles Wilder’s home and museum.
