The Rosa 'Oklahoma' is a dark red rose variety with a strong and sweet fragrance. The hybrid tea rose was developed at Oklahoma State University by Herbert C. Swim and O. L. Weeks before 1963 and introduced in 1964. It was hybridized from the cultivars 'Chrysler Imperial' and 'Charles Mallerin'. In 2004, the Oklahoma Rose became the official state flower of Oklahoma.

The hourglass selenite crystal can be located in the Salt Plains National Wildlife Refuge. Oklahoma is the only place in the world where the hourglass-shaped selenite crystal can be found. Crystal digging in this area is open from April 1 to October 15 from sunrise to sunset. Located just under the surface of the wet salt plains, sand and clay particles are included within the crystal. These particles often form an "hourglass" shape inside the crystal. The Hourglass Selenite Crystal was adopted in 2005 as Oklahoma's State Crystal. The hourglass variety of selenite is said to be used for grounding and raising awareness, and helps release negative patterns.

The flathead catfish, also called by several common names including mudcat or shovelhead cat, is a large species of North American freshwater catfish in the family Ictaluridae. It is the only species of the genus Pylodictis. A flattened head, tiny eyes, squarish tail and protruding lower jaw distinguish the flathead from other catfish and contribute to it being placed in a genus of its own. They are yellow-brown and usually mottled above, with a creamy-white or yellow belly. Flatheads are found mainly in large rivers and their major tributaries and just about every lake in Oklahoma.

The downy woodpecker is the smallest woodpecker in North America, although it avoids the arid southwest. Downy Woodpeckers are found year-round in Oklahoma, in open woodlands and forests. They tend to favor deciduous trees, but they can also be spotted in backyard, parks, and other residential areas. They’re very active during spring and summer, hammering into trees and making their characteristic high pitched calls.

In 1951, the scissor-tailed became Oklahoma's state bird. Scissor-tailed flycatchers are easily identified by their long, scissor-like tail, which may reach nine inches in length. During flight, the bird opens and shuts its tail like a pair of scissors and folds or closes the “scissors” when perching. Since the bird is only 11-15 inches long, its tail is proportionately longer than any other Oklahoma bird. In Oklahoma, scissortails often are seen in open prairies dotted with trees and along tree-lined country roads. They also appear in open country around ranches and even small towns, where they perch on telephone lines, flagpoles and fences.

The magnolia flower meaning is attached with the symbols of nobility, perseverance, and love of nature. Soft and subtle in color yet strong in appearance, the flower is representative of the beauty encompassing femininity and gentleness. Purple Magnolias in particular are said to send out vibrations that help in achieving wishes of luck and health.

The magnolia flowers bloom boldly and are large in size, add to this their subtle, yet pleasing colors and they make for a thing of beauty. But what really enhances their beauty further is the distinct fragrance that they emanate―all these features lend them the meaning of splendid beauty and magnificence. The magnolia flower meanings are both, interesting and intriguing and have a rather fascinating history associated with them. Their meaning varies according to the different cultures and locations, because the magnolia plant varieties are native to both Asia and the Americas.

Oklahoma designated the black swallowtail as the official Oklahoma state butterfly on November 1, 1996. Oklahoma is a home to a wide variety of colorful butterflies. The black swallowtail is a migratory species indigenous to the state from May to October.

The Eastern Redbud was adopted in 1937 as the Oklahoma state tree. The Eastern Redbud grows in the valleys and ravines of Oklahoma. In early spring, its reddish-pink blossoms brighten the landscape throughout the state. Genus name comes from the Greek word kerkis in reference to the resemblance of seed pods to a weaver's shuttle. The splendid purple-pink flowers appear all over the tree in spring, just before the leaves emerge. The flowers can be eaten fresh or fried.

Paddlefish are one of the most unique fish in Oklahoma. They can live up to 50 years and range throughout the U.S. from Montana to Louisiana. In Oklahoma, they are found mainly in the Grand Neosho and Arkansas river systems. In 1992, fisheries biologists began an effort to re-introduce paddlefish to waters where they had become locally eradicated. Hatchery professionals raised young paddlefish in Byron and Tishomingo and then released them in Kaw, Oologah, Texoma, and Hugo lakes. On June 28, 2020, an Oklahoma man caught a 146-pounder in Keystone Lake, west of Tulsa. Later, on July 23, 2020, the record was broken again when another Oklahoma man caught a 151-pound, nearly 6-foot long Paddlefish in the same lake.

Art Deco, sometimes referred to as Deco, is a style of visual arts, architecture and design that first appeared in France just before World War I.[1] Art Deco influenced the design of buildings, furniture, jewelry, fashion, cars, movie theatres, trains, ocean liners, and everyday objects such as radios and vacuum cleaners.[2] It took its name, short for Arts Décoratifs, from the Exposition internationale des arts décoratifs et industriels modernes (International Exhibition of Modern Decorative and Industrial Arts) held in Paris in 1925.[3] It combined modern styles with fine craftsmanship and rich materials. During its heyday, Art Deco represented luxury, glamour, exuberance, and faith in social and technological progress.
