Petal tips are adorned with clean white spots. Flowers of the proposed variety consist of densely packed large, whorled petals and take on a light, juicy, orange colour. Its large compound leaves that consist of small oval leaflets, create a magnificent, subdued background for the unique bicolour flowers.
This vigorous and reliably flowering perennial grows 90 to 110 centimetres tall. This becomes extremely important for growers and those competing in breeding competitions.įor those of us that simply enjoy the magnificent flowers, it is a fun way to describe some of the original forms of the amazing dahlia.The Colour Spectacle dahlia (Dahlia) belongs to the largest varieties of this popular garden plant.
In this way, the explosion of hybrids can be set into their individual class for an easier understanding of their origins and parent. There are also miniature at 1 ½ to 4 inches (4-10 cm.) and pompoms, which grow less than 1 ½ inch (4 cm.) in diameter.Įach of these is also divided into the cactus, colarette, or anemone, orchid, waterlily, stellar, and ball distinctions.Medium flowered varieties are just under 8 inches (20 cm.) while small flowered varieties may one grow 4 inches (10 cm.) in width.The large flowered category gets just under this size at 8 inches (20 cm.).The biggest flowers are in the giant category and may get nearly 10 inches (25 cm.) in diameter.Blooms with creased petals are in the stellar class and those with a closed center and flat, broad rows of ray florets are in the waterlily designation.Īnother way to order the different types of dahlia is by using their bloom sizes.
Orchid and peony are open centered flowers with one or more rows of ray flowers around a disc. Each has a star-like appearance with flat petals and a distinctive disc. A broad class is the singles, semi-doubles, colarettes, and anemones. These blooms have incurved or rolled petals that are nearly straight. Cactus types of dahlia flowers are one of the showiest. The ray petals are blunt and may be quill-like. Round ball-shaped flowers with double flat spirally arranged petals. Pompoms and balls are just what they sound like. Decorative types may be informal or formal and bear blooms thick with petals that are usually flat but may be rolled. This way of dividing the species is poetic and requires observation. This method is a quick and fairly unsophisticated way to tell a class just by eyeballing the blooms. The other method of separating the varieties of dahlia is by delineating by flower size. These indicate the shape of the flower and occasionally the character of the petals. Once you start trying to tell the difference between the species and hybrids, all other similarities become more vague.ĭahlia varieties are divided into flower form classes. Plants require sun, well-drained soil, plenty of water, and good air circulation. Most are small to large bushes with deeply cut leaves that stem from tubers. The actual appearance of a dahlia plant is very similar among species. The only way even expert growers can keep them all straight is by ordering the types of dahlia flowers into groups. The different types of dahlia are astounding and mind numbing in their excess. The results are an ocean of color with amazing forms across the area. Serious collectors and hobbyists breed specific forms in an attempt to outdo each other on size and spectacle. Here you can see a vast array of dahlia plant types, represented by their flowers. If you have ever been to a county fair, one of the biggest attractions is often the dahlia building. Varieties of dahlia are divided by size and classes by flower shape. There are six dahlia varieties and seven form classes. There still may be uncountable hybrids and cultivars within each class but at least it helps group them in an organized system. Dahlias are classed by their flower type and size. These Mexican flowering bushes are popular for their diversity of size and form. There are 42 species of dahlia but innumerable hybrids.
