Performance
Missouri Evening Primrose has eye-catching large, yellow flowers. In addition, the seed pods add late season interest. It needs little care, but flea beetles frequently chew holes in the leaves. Flea beetle damage can disfigure the plant extensively for a growing season, but only occurs in large numbers every few years.
Maintenance
In early spring, cut the old growth to ground level.
