A town steeped in history & gardens

Summerville lies about 24 miles northwest of Charleston. Nicknamed “Flowertown in the Pines,” it’s known for its springtime displays of azaleas, wisteria and dogwoods. The annual Flowertown Festival—held each April in Azalea Park, a 12‑acre oasis with ponds, fountains, tennis courts and sculptures—draws thousands of visitors and more than 200 vendors, making it one of the largest arts and crafts festivals in the Southeast. Summerville also celebrates its status as the “Birthplace of Sweet Tea.” Tea plants were first cultivated in the area in the late 1700s, and Dr. Charles Shepard’s Pinehurst Tea Plantation, established in 1888, became the first successful commercial tea farm in the United States. Today, the town honors this heritage with a Sweet Tea Festival, a Hold My Tea Bar Crawl and a Sweet Tea Trail. Visitors can even see “Mason,” a 15‑foot‑tall sweet tea jar near Town Hall that set a Guinness world record by holding 2,524 gallons of iced tea.

Beyond festivals, Summerville boasts over 700 buildings on the National Register of Historic Places, plus boutique shops and restaurants along Main Street.
