Missouri Primrose is a sun loving member of the primrose genus that is native to the southern Great Plains from Texas to Nebraska and Missouri. Preferring dry open prairies with rocky or sandy soils, it does not compete well with taller plants due to its short growing height. Its deep taproot allows this perennial the ability to be quite drought tolerant. The large yellow flowers are in bloom from May-July, usually only for one day, opening in the afternoon and closing the following morning. An attractant for many nocturnal pollinators, especially the sphinx moth. Recently, botanists changed the scientific name to Oenothera macrocarpa.
