Dahlias are perennial herbaceous plants, sometimes woody at the base stems something rarely climbing epiphytes (Dahlia macdougallii). They form tubers or rhizomes tuberous thickened as Überdauerungsorgane. You can, for example, Dahlia imperialis be up to 8-10 meters high. Dahlia macdougallii forms aerial roots. The upright, usually unbranched stems are individually, in pairs to four or numerous in bundles depending on the section.
