Big dinner plate size and easy to care for. Better flower production then other giant dahlias. Bloom size is big but plant size remains short. Will not hesitate to replant next yr.

I have grown Kelvin Floodlight in Vermont and in Michigan. Unlike most A or AA dahlias, this dinnerplate blooms very early, so is especially suitable for northern gardens. We plant a row of them in our front yard and they definitely get attention.

I accidently left this plant in the ground and it was just beautiful this year. I believe in the area I live, I should not leave Dahlia's in ground. But because of the success with this plant, I have left all the Dahlias in the ground this winter to see how they do. I do have trouble with this plant being too prolific of a bloomer. It's hard on the plant, so I have learned to pick off buds here and there so the plant stays healthier that way. The blooms are 8" at least. Update to post I previously made: I have since learned that in my zone, Dahlia's can be left in the ground and they all have come back and are better than last year. I will leave them in the ground from now on.

Beautiful long lasting bright yellow blooms. Mine generally reach about 8" - 10" across. I find mine do best when planted in containers (instead of directly in garden) in full sun with rich, loose, well drained soil. Give a spritz of liquid fertilizer once ever couple of weeks. Plant the bulbs at about 6" depth.

Absolutely beautiful, dependable dahlia that I've grown for the last 5 years. Since I'm in zone 5, I set the bulbs out in May (usually mid month). If frost is possible, cover tender vegetation on those nights with a cardboard box or remay cloth. Blooms generally appear by the end of June/ early July and continue until frost. When frost arrives, lift bulbs, cut off plant close to top of bulb, clean off with water and put in airy place to dry. I store mine in my... read more

These flowers were huge! Truly dinnerplate sized. Easy to care for also; I live in Z7 and dont have to dig them up, but should since they always need dividing. They are very vigorous.

In warmer climates you maybe able to leave the tubers in the ground with heavy mulch. But for me in Zone 6 I have to dig the tubers before first frost.Clean and let dry good.Pack in dry peat and store in cool dry place.
