Dahlia, cactus and semi-cactus

With the cactus dahlia the ribbon flowers have rolled for more than two thirds. The petals of flowers of the type of cactus can both be straight, but also bend inward or outward. The petals are usually narrow and pointed, sometimes the tops are deeply cut. In the semi-cactus dahlias, the flowers are completely filled and the ribbon flowers are slightly broader and flatter than the true cactus. They are flat or slightly bent. The petals are rolled for less than half the length.
