Plant Information

The Mystery Day Dahlia is one of the most popular Dahlias of all time. It has been a favorite of Dahlia lovers for decades, for its brilliant color combination and beautiful representation of the double Dahlia form. Dahlias put on a stunning show both in the garden and cut to bring inside for flower arrangements. With dozens of varieties to choose from, you can literally plant any color combination in your sunny garden for a delightful, stunning show. Try different varieties for a unique combination of blooms in your garden this summer until fall. Dinnerplate Dahlias are, simply put, the large plants with the huge flowers. The always-double flowers are up to 8", sometimes a whopping 10" across, so the name makes sense.

Decorative Dahlias This group includes the Dinnerplates and also other taller (to 4 ft.) plants with double, chrysanthemum-like flowers.

Growing Dahlias: All the gardener needs to do is plant the tubers after spring frosts in good garden soil with full sun. It's best to position them against a wall or be ready to stake them, since they are brittle, and must be protected from high winds. (If you've grown perennial Delphiniums, the plant size and growth is similar, but success with Dahlias is much easier.) Keep them free of bugs, well-watered, and well-fertilized as they grow, and your dahlias will begin to set buds by midsummer and be in full bloom, usually during July or August. Then the huge flowers keep coming until frost.

When frost threatens, just pull the roots up, cut off the stems, and store the tubers until the following spring. Each fall, you'll be amazed how the 'bulbs' have multiplied during the summer, giving you more and more to divide and enjoy the next year.

One expert has said, "Never have so many gardeners received so much for so little work, as when they grow dahlias.''

I've been very satisfied with the plants that I've purchased from rather American Medows, however, this time the Dahlias weren't as described at all. They were described as dinner plate size and they were smaller than saucers. Unfortunately, I gave one package of the bulbs to one of my friends as a present and became very embarrassed when she told me that hers were very small too.

        Comments about American Meadows Dinnerplate Dahlia Mystery Day:

        In past years I have had prolific blooms from this variety of dahlia, but this year, the plant was small and I don't recall ever getting a single bloom from that plant. Most of my dahlias produced minimal amounts of flowers. I usually use them in arrangements which I sell at a roadside stand, but not this year.

            I only bought 9 bulbs, but not a single one of them grew. I expect a small percentage to be duds, but hoped to get at least a couple of blooms. Alas, at least I know to avoid these next time.

            Comments about American Meadows Dinnerplate Dahlia Mystery Day:

            Got three, each, of three different dahlias--only seven came up. All planted in same 4' x 4' plot. Wanted to make sure that conditions were the same for them all for the first season. Never saw a bloom from this one.

                  USDA Hardiness Planting Zones

                  To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

                  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
                  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
