Decorative Dahlias

Decorative Dahlias, Decorative Formal Dahlias, Decorative Informal Dahlias


Dahlias 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.

They are available in a rich variety of bloom colors, shapes and sizes. Flowers can be as small as 2 inches in diameter or up to one foot. They can be single-flowering (orchid-flowering, anemone and collarettes) or double flowering (cactus, semi-cactus, formal or informal decorative dahlias, ball and pompons). Their wide height range can start as low as 12 inches and go up to 6 feet.

Decorative Dalhlias are double dahlias with broad, flat-tipped petals that are sometimes wavy. The flowers are normally large and the plant size varies from 6-7 ft. giants (2 m) to compact bedding dahlias that grow only 15 in. high (38 cm). 

Decorative Dahlias can be formal with flat petals evenly and regularly placed throughout the flowers, or informal with generally flat petals, sometimes slightly rolled at the tips, but with irregular arrangement of formation.

All these Decorative Dahlias are knockouts. If grown for the vase, choose the formal decorative varieties with their perfectly packed blooms. The informal decorative dahlias will look terrific in your borders or containers.

There are hundreds of formal and informal Decorative Dahlias (!!!). Here is the list of our favorite Decorative Dahlias.
