Irmo was incorporated in 1890 and has flourished along the tracks of Columbia, Newberry and Laurens railroads. The name of Irmo was derived from the surnames of two railroad officials, C.J. Iredell and H.C. Moseley. Divided by Richland County on the northwest and Irmo County on the southeast Irmo is located off the shore of Lake Murray and only ten miles from Columbia, the state capital. Irmo has grown from a sleepy little town into an area bustling with excellent shops, restaurants and specialty stores. The last weekend in September is home to the famed Okra Strut, the largest known celebration of the slimy green pod.
