Cactus & Semi Cactus Dahlias for Sale

The Best Cactus Dahlia Varieties

We group semi-cactus and cactus dahlias together - both are fully double and vary in size from small to giant, while their "spiky" shapes mean that rain weighs them down less, so they do not need as much staking as types with heavier heads. Together, cactus and semi-cactus dahlias are among the most striking dahlias available.

Cactus dahlias have petals that are narrow at the base and that frequently curve inwards while the petals on semi-cactus dahlias are broader at the base and are typically rolled in for part of their length. For broader petalled beauties, have a look at the rest of our of dahlias.
