The Ohio State Flower and Its Official Designation and Adoption in 1904
The Ohio state flower was officially designated in 1904 by the Ohio General Assembly. The decision followed discussions about selecting a floral symbol that represented the state and its historical background. The scarlet carnation was selected because of its strong association with President William McKinley. McKinley was born in Niles, Ohio, and later became the 25th President of the United States. He was closely linked to the carnation during his political career.
The adoption of the Ohio state flower was also influenced by public sentiment after McKinley’s assassination in 1901. The flower had already become associated with his public image, which made it a natural choice for official recognition. Since 1904, the scarlet carnation has remained the official Ohio state flower without changes.
Connection to William McKinley
The history of the Ohio state flower is directly connected to President William McKinley. McKinley, who was born in Ohio, frequently wore a red carnation on his coat during public appearances and political speeches. Over time, the flower became closely associated with his public image and personal identity, and both supporters and the general public widely recognized it.
After McKinley was assassinated in 1901, the carnation gained additional meaning as a symbol of remembrance and respect. This association played a key role in Ohio’s decision to adopt the flower as the official Ohio state flower. The connection between McKinley and the scarlet carnation remains the central reason for its selection and continues to define its historical importance.
The Scarlet Carnation as the Ohio State Flower
The scarlet carnation is the specific flower recognized as the Ohio state flower. It belongs to the species Dianthus caryophyllus and is identified in official state usage by its red color. The Ohio state flower refers specifically to the scarlet variety of carnation rather than other colors, such as white, pink, or yellow, that exist within the same species. This distinction is important in official references, where only the scarlet form is used to represent the state.
The scarlet carnation is known for characteristics such as its structured petal formation, its strong red coloration used in symbolic representation, and its suitability for ceremonial arrangements. It also has a long history of cultivation as an ornamental plant. Because of these features, the scarlet carnation remains the standard representation of the Ohio state flower in official and educational contexts.
Botanical Characteristics of the Scarlet Carnation
The scarlet carnation, which represents the Ohio state flower, is part of a plant species that has been cultivated for centuries. It is recognized for its layered petal structure, its strong stem that supports floral arrangements, and its adaptability to different growing conditions. These qualities have made it a widely used ornamental flower in many regions.
While carnations exist in multiple colors, only the scarlet variety is recognized as the official Ohio state flower. This specific selection is what gives it its symbolic and official status, distinguishing it from other types of carnations used in gardening and decoration.

The Ohio State Flower and the Historical Background of the Selection
The selection of the Ohio state flower took place in the early 1900s, during a period when many U.S. states were establishing official symbols to represent their identity. At the time, the carnation was already widely recognized in Ohio due to its association with William McKinley, and it was also a common ornamental flower in public and private gardens.
Because of its strong cultural presence and symbolic connection to a prominent Ohio figure, the scarlet carnation was approved by the Ohio General Assembly in 1904 as the official Ohio state flower. The decision reflected both public sentiment following McKinley’s death and the desire to select a symbol that represented the state’s heritage. Since its adoption, the Ohio state flower has remained unchanged, making it one of the more consistent state floral symbols in the United States.

The scarlet carnation is commonly associated with respect for public service, remembrance of historical figures, recognition of leadership, and connection to state heritage. These meanings have strengthened its role as a symbol of Ohio identity over time. Because of this symbolism, the Ohio state flower is often included in educational materials and civic programs across the state. It is used as a reference point in teaching about Ohio history, state government, and civic identity, helping reinforce its meaning beyond its botanical characteristics.
Modern Recognition and Continued Use of the Scarlet Carnation
