Cactus and Semi Cactus Dahlias

Cactus Dahlias for Sale

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. If you prefer broader petalled dahlias, please look at the rest of our of dahlias for sale where you find other shapes and sizes aplenty!
