Cactus Dahlias, Semi Cactus 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, anemones, and collarettes) or double-flowering (cactus, semi-cactus, formal or informal decorative dahlias, balls, and pompons). Their wide height range can start as low as 12 inches and go up to 6 feet.
Cactus and semi-cactus dahlias feature double flowers with long pointed ray petals that revolute or roll back along half their length, giving the flowers a spiky look. Their blooms come in many sizes and most cultivars reach a height of more than 40 inches.
Dramatic-looking, their star-like flowerheads stand up well to inclement weather, since they are less weighed down by heavy rain, or blown about by wind, than other dahlia types.
There are hundreds of Cactus and Semi-Cactus Dahlias (!!!). Here is the list of our favorite Cactus and Semi-Cactus Dahlias.
