Cactus and semi-cactus dahlias

Discover some stunning spiky cactus and semi-cactus to grow - perfect for borders and the vase.

Some of the most spectacular dahlias are cactus and semi-cactus types. With their spiky petals, they can trace their lineage back to a single surviving plant grown from a crate of tubers imported into The Netherlands in 1872.

Cactus dahlias are some of the most dramatic types . Their star-like form means they stand up well to inclement weather, because they're less prone to being weighed down by heavy rain, or blown about by wind, than other dahlia types.

Cactus dahlias also need less staking than other varieties, which tend to have dense, heavy heads of petals.
