Oklahoma’s amazingly diverse flora has long been of interest to state residents. In 1987, individuals from throughout the state founded the Oklahoma Native Plant Society to encourage the study, protection, propagation, appreciation, and use of the state’s native plants. The society’s varied activities (field trips, lectures, workshops, displays, inventories, and roadside plantings) promote an awareness and understanding of some of the state’s most valued treasures.
Botanically, Oklahoma is a remarkable state! Located at the juncture of several physiographic provinces, it is indeed an ecological crossroad. Within its borders are found ~175 families, ~870 genera, and approximately 2,600 species of vascular plants—flowering plants, conifers, ferns, horsetails, and clubmosses. This flora is a complex assemblage of plants representative of different phytogeographic regions. Species characteristic of the eastern deciduous forest and central grasslands are the most common; however, species from the Rocky Mountains, the Chihuahuan and Sonoran Deserts, the Gulf Coastal Plain, and the Ozark Mountains also occur in the state. Fourteen different vegetation types are traditionally recognized. This tremendous diversity of plant species and communities reflects the considerable variation in the state’s climatic, physiographic, geological, and edaphic features. A plethora of different habitats for plants are present. More information about the flora of our great state can be found at the Flora of Oklahoma Project page.
