The Alomar house and gardens on St. Marys Road in Columbus, Georgia, was built in the 1930s. The gardens and grounds were designed by well-known Atlanta architect William C. Pauley (1893-1985). The home took its name from portions of the original owner’s name, Alfred Owen Blackmar III (1884-1944). The Blackmar family were early residents of Muscogee County, and Blackmar managed his family's business. He married Mary Gordon (1884-1954) in 1910, and they had two children: Margaret “Peggy” Blackmar Howard (1915-1985) and Alfred O. Blackmar IV (1912-1968).

The gardens included a tea house, ponds, and stone wall with potting shed. The Blackmars were renowned for their gardens, particularly their daffodil, camellia, and orchid collections. They were active members of several garden clubs and flower shows, using their home as the centerpiece for garden tours and social events.

Following the death of Alfred Blackmar in 1944, Mary Blackmar remarried William H. Crawford (1886-1975) and continued managing the gardens and home tours alongside her daughter, Peggy Howard, until Mary’s death in 1954. Peggy and her husband, Colonel Claude M. Howard (1909-1999), lived at Alomar, and the gardens continued to be featured in garden events. Their son, Stephen Howard, and his family resided at Alomar until they sold the home in 1995.
