Dahlia coccinea

Scarlet Dahlia (Dahlia coccinea)

The Scarlet Dahlia (Dahlia coccinea ) is a plant of the genus Dahlia (Dahlia ) in the sunflower family ( Asteraceae).

Features

The Scarlet Dahlia is a perennial herbaceous plant with a rhizome and tuberous roots (up to 50) reached the heights of growth of mostly 100 to 200 centimeters. The stem is bare or has only stiff hairs below. The leaves are twice pinnately divided, the leaf margin is ciliated and the midrib not or scarcely winged.

There are usually two to three flower baskets available, rarely only one. The eight ray flowers are 1.5 to 4 inches long and yellow, orange or red. The species is very rich in form.

The flowering period extends from August to September.

Occurrence

The Scarlet Dahlia comes from Chihuahua and Coahuila in Mexico south to Guatemala in the mountains and on the plateau at altitudes from 800 to 2500 meters in front. It grows in open oak, pine and ravine forests to grassy- rocky or gravelly slopes, on lava flows or streams.

Use

The Scarlet Dahlia is rarely used as an ornamental plant in rebates. It is in culture at least since 1798. Today's dahlia hybrids go on intersections of scarlet Dahlia and Großfiedrigen dahlia ( Dahlia pinnata ) back.
