Since 1964. *Exact bloom times may vary depending on weather conditions. For peak bloom times, visit Mum Watch on the website in early November. Hundreds of colorful four-foot long cascades will be displayed on bridges and balconies, in baskets and containers through the Gardens. Guests will also enjoy the columns of mums and thousands of mums in the flower beds in the fall colors of yellow, red, bronze, orange and white. The Great Lawn’s dramatic border will be a feast for the eyes. Bellingrath’s Mum show is one of the grandest in the country. All of the cascades are grown at Bellingrath. Moving the cascades into the gardens is one of the most spectacular horticultural events of the year. It takes over nine months to grow a single crop – a true labor of love by Bellingrath’s expert growers.
