Dinnerplate Dahlia ‘Kelvin Floodlight’ is a huge, bright yellow flowered Dahlia with individual flowers 7 to 8 inches in diameter. These beauties make stunning, long lasting cut flowers. Cold hardy in zones 8-10. In colder zones lift the bulbs in fall and store in a cool place over the winter.
Planting & Care
Summer Blooming Bulbs, including popular varieties such as gladiolus and dahlias, are planted in the spring and bloom in the summer. Most of these bulbs are tropical and require warm weather to be planted. There must not be any danger of frost and your ground temperature must have reached 55 degrees Fahrenheit before planting. Many
of our summer blooming bulbs can be planted as perennials in zones 9-10 (zone 8 if mulched), but should be treated as annuals in cooler climates. You can lift them and store them in the fall, or bring patio pots inside before frost. Read our article about How To Grow Dahlias.
Growing Dahlias: Plant Dahlia tubers after spring frosts in good garden soil with full sun. Dahlias must be protected from high winds, so we suggest you position them against a wall or be ready to stake them. Keep the plants well-watered and free of bugs, applying flower fertilizer as they grow. Your dahlias will be in full bloom by July or August, with the enormous flowers continuing to bloom until frost. As frost threatens, pull up the roots and trim off the stems. You can store the tubers in a cool dry place until the following spring.

"Nice big bulbs. Already has green coming out of the top. Just buried them so hopefully they will take off soon. My Husband wanted these as a memorial for his mom so I hope there like the picture very hope full and all in all extremely happy with HCG! Going to get a tomato cage for support as it grows."

Exquisite!!!
"These dahlias have been an absolutely stunning addition to my garden. They began blooming in Aug and never stopped! Truly the most beautiful (and gigantic) flowers I have ever grown. I am in zone 6 and dig up the tubers in fall and replant in May. I highly recommend!"
