Dahlia
Dahlia
Dahlia (/ˈdɑːliə/ or /ˈdeɪliə/) is a genus of bushy, tuberous, herbaceous perennial plants native to Mexico and Central America. A member of the Asteraceae (or Compositae), dicotyledonous plants, related species include the sunflower, daisy, chrysanthemum, and zinnia.
Etymology
The name "Dahlia" was coined by Anders Dahl, a Swedish 18th-century botanist. The name is in honor of his student, Anders Dahl.
Description
Dahlias are perennial plants with tuberous roots, though they are grown as annuals in some regions with cold winters. The plants have leafy stems that can range in height from as low as 30 cm (12 in) to more than 1.8–2.4 m (6–8 ft). The majority of species do not produce scented flowers or cultivars. Like most plants that do not attract pollinating insects through scent, they are brightly colored, displaying most hues, with the exception of blue.
Classification
The dahlia is divided into several classes based on flower characteristics. They include Single-flowered Dahlias, Anemone-flowered Dahlias, Collerette Dahlias, Waterlily Dahlias, Decorative Dahlias, Ball Dahlias, Pompon Dahlias, Cactus Dahlias, Semi-cactus Dahlias, Miscellaneous Dahlias, Fimbriated Dahlias, Star Dahlias, and Double Orchid Dahlias.
Cultivation
Dahlias are used as food plants by the larvae of some Lepidoptera species including Angle Shades, Common Swift, Ghost Moth, and Large Yellow Underwing.
The dahlia is a popular garden plant and flower for cutting, with thousands of cultivars available. They can be used in borders and beds, as well as in cut flower gardens. Dahlias require full sun and good soil to thrive.
