Cactus and Semi-Cactus Dahlias
Cactus dahlias are by far the most dramatic of all dahlias. These blooms are double-flowering with long, rolled petals, giving them a spiky look. These types of dahlias feature a variety of colors and can range from miniature flowers to giant blooms. Cactus types are classified as incurved cactus, straight cactus, and semi-cactus. Incurved cactus types have petals that are completely rolled with the tips curving toward the center of the flower. Semi-cactus blooms feature petals that are only half-rolled and are flat at the base. Finally, straight cactus have straight petals that are rolled for one-half of their length.
Some popular cactus and semi-cactus dahlias include:
Dahlia ‘Doris Day’
This is the largest category of dahlias and offers a wide variety of colors and shapes. Unlike the cactus types, decorative dahlias have broad and flat petals. These versatile blooms are double-flowering and they are either classified as formal or informal. Informal decorative dahlias have petals that are evenly and regularly placed while informal types have flat petals that are slightly rolled at the tip and are placed irregularly.
Some popular decorative dahlias include:
