Kelvin Floodlight Giant Dinnerplate Dahlia Has Moved On — Shop Dahlias at Coast Farms
Dahlia ‘Kelvin Floodlight’ is a spectacular dinnerplate dahlia, renowned for its enormous, fully double golden-yellow blooms that can reach an impressive 10–12 inches across. This award-winning variety produces bold, sunlit flowers on sturdy stems, creating a dramatic focal point in garden beds, borders, and cut flower arrangements.
Blooming from mid-summer until the first frost, this tall, vigorous plant (typically 3–4 feet high) delivers long-lasting colour and attracts pollinators like bees and butterflies, making it a favourite for both landscape impact and floral displays.
