Plant Family Guides: Dahlias
Single Dahlias feature blooms with a single row of flat or slightly cupped ray florets arranged in a flat plane, uniformly overlapping, preferably in the same direction with no gaps. The disc flowers may have up to three rows of bright yellow or orange pollen and the blooms are over two inches in diameter (5 cm). Pollinators love these Single-Flowered Dahlias!
The flowers of Dinner Plate Dahlias make quite an impression! They are unbelievably large - up to 12 in. across (30 cm) - and will bloom continuously from July until the first touch of frostDahlias are absolutely breathtaking flowers. Flowering for months, they inject color and drama wherever you grow them: in mixed borders in the garden, in containers or window boxes on balconies and on patios
Pompon and Ball Dahlias feature relatively small, fully double, globe-shaped flowers with petals blunt or slightly rounded at their tips. How not to marvel at the perfect petal arrangement of these dahlias? They display an infinite swirl of florets with fold upon fold of incredibly flawless petals.
Anemone Dahlias feature an outer ring of flat ray petals arranged in a wreath and surrounding masses of tiny, elongated disk florets which form an intriguing floral pincushion. Collarette Dahlias are small to medium flowers with large flat ray petals surrounding an open center. Within the ray and surrounding the center is a wreath of shorter petals, often of a different color: this forms the “collar.”
Peony Dahlias are open centered flowers with two or more rows of large and voluptuous petals surrounding a disc. Orchid Dahlias are also open centered flowers with one ray of florets surrounding a disc (Single Orchid) or a fully double bloom showing no disc (Double Orchid). The florets involute for two-thirds or more of their length.
Fabulous planting partners for dahlias, ornamental grasses help create incredibly beautiful planting combinations. In contrast with dahlias which boldly inject bright colors and broad-petalled flowers in the garden, grasses contribute their beauty in a more subtle fashion through their transparency, luminosity, texture and seasonal changes.
Injecting color, drama and late-summer fireworks in the garden, dahlias look fabulous on their own or combined with other plants. Many are graceful and integrate well into most borders, creating appealing planting combinations and providing interest from mid summer until the first frost.
