Mignon and Single 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!

Anemone and Collarette Dahlias

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-Flowered and Orchid Dahlias

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.
