Junius G. Groves was born enslaved in Green County, KY, the son of Martin and Mary Anderson Groves. Junius was the husband of Matilda E. Stewart Groves; they were the parents of 14 children.

The story of Junius Groves has been retold many times. He walked to Kansas City in 1879, where he worked for 40 cents per day. Groves was able to save enough money to purchase a nine-acre farm in Edwardsville, KS, enabling him to later purchase a 500-acre produce farm there. At one time he produced more potatoes than any other farmer in the world, the harvest so large that a private railroad track was built on his land by Union Pacific Railway for shipping the produce. Groves was known as the "Potato King of the World."

He also founded the community of Groves Center, KS, in 1913, he had a grocery store and a golf course built for African Americans. He helped found the Negro Business League, the Baptist Church, and other organizations for African Americans.

In 1925, the Junius G. Groves estate was valued at $100,000, including, it was said, 400 acres in Wyandotte, Kansas and 1,200 acres in Western, Kansas; the land was not to be divided. Junius G. Groves was said to be one of the wealthiest African Americans in the United States in the early 1900s.

Just prior to his death in 1925, though, he had a lot of debt and there was a foreclosure brought on the home he and his wife Matilda built in 1910. The structure had three levels with 22 rooms. There was a fire at the home in June 1964; the building could not be saved. At the time of the fire, the house was owned by Mrs. Corinne E. Smith and was valued at $50,000. 

Many, many articles have been written about Junius G. Groves. In 2021, a special ceremony was held for his induction into the Kansas Business Hall of Fame.
