The species is very thermophilic, prefers sunny areas and nutrient-rich soil. Here are some common representatives of this group:
Inflorescences of collar( cuff) dahlias consist of two rows - external, represented by large dark petals, and internal, with pointed petals of lighter tones. The number of petals in the rows, as a rule, coincides. Both rows come from a common bright yellow core. The height of plants varies between 0.5-2.5 meters, the diameter of flowers - from 5 to 15 centimeters. Classical collar varieties include:
Recently, there are many unusual varieties of collar dahlias. The color of their petals can vary in a very wide range - from light green to purple.
Decorative dahlias are large-flowered and tall, forming heapy, tall bushes. This species is the most diverse both in the number of varieties, and in the color range and number of forms. The diameter of the inflorescence of decorative dahlias is not less than 10 centimeters, in some varieties reaches 30 centimeters. The petals can be flat and tubular, straight and curved, large and small, arranged in rows or spherical. Here are the most magnificent and beautiful varieties of decorative dahlias:
Cactus dahlias are not only incredibly beautiful, but also very practical. Their dense petals resemble long thick needles and diverge in all directions from the core. This form ensures the unpretentiousness of plants to weather conditions, even strong wind and rain can hardly break or tear such a flower. Cactus dahlias with wider petals( width 2 and more times thicker) are also called half-cactus dahlias. Among the representatives of the species there are also dwarfish dahlias( 20-50 centimeters), and giants up to 2.5 meters high. The diameter of the flower is usually within 10-25 centimeters. Here are the main varieties of cactus and semi-cactus dahlias and their characteristic color:
Lotus-shaped dahlias are characterized by delicate, delicate petals curved upward. Inflorescences are bulky, but not spherical, with a diameter of not more than 20 centimeters. Flowers are unusually beautiful, so most often they are grown on a slice and used in single or multicolour bouquets. Nymphaeous dahlias are demanding for the quality of the soil, they are suitable only for light soils without significant mechanical impurities, enriched with minerals and organic. The following species refer to the species:
Simple dahlias are a universal garden plant with a height of 20 to 100 centimeters, which perfectly fits most other colors and will look good on any flowerbed.

The most common are 3 varieties:
Varieties are very similar, which often leads to confusion and frustration, especially among beginning florists. Their main difference lies in the size of the inflorescences and the density of the petals. The height of the bushes in the species is the same - from 90 to 120 centimeters.

Flowers of globular dahlias are larger than their pompomous relatives, the diameter is 8-15 centimeters. In addition to the spherical, a slightly flattened shape occurs, and the tubular or semitrubular petals are somewhat more sparse. Bright representatives of spherical dahlias are:
So called rare varieties, the form of which does not fall under the description of any of the listed species.
