The first plant was called Dahlia pinnata after its pinnate foliage; the second, Dahlia rosea for its rose-purple color. In 1796, from the parts sent by Cervantes, Cavanilles flowered a third plant, which he named Dahlia coccinea for its scarlet color. In 1798, Cavanilles sent D. pinnata seeds to Parma, Italy.

The plant is about 1 m tall and flowers from June until September.
A ray flower is a two- or three-lobed, strap-shaped, individual flower, found in the head of most members of the Asteraceae. [15] [16] The corolla of the ray flower may have two tiny, vestigial teeth, opposite to the three-lobed strap, or tongue, indicating its evolution by fusion from an ancestral, five-part corolla. In some species, the 3:2 ...
