The leaves have a corded oval shape, the basal ones up to 15 cm in size with a 10-30 cm petiole, the lower caulins more or less panduriform in shape, the upper ones from cordate to lanceolate amplessicauli.
The flowers are yellow in color grouped in irregular corymbs from 2 to 10 flower heads with a diameter of 3-5 cm. Flower head with disc-shaped casing and slightly enlarged scales almost to the apex; hermaphroditic tubular internal flowers, female ligulate external flowers.
The antesis is between May and August.
The fruits are Cypseles (achenes), obulong-obovoid, blackish brown, grooved, dimorphous: those with a radius of 1,5-2,5 x 07-1,3 mm, glabrous, without pappus; those of the disc of 1-2 x 0,4-0,8 mm, hairy, with pappus of white hairs of 3-4 mm.

Cultivation –
The Leopard’s-bane is a plant that grows spontaneously and that can be grown in the sun or in dim light on soils that are preferably humid and rich in organic substance.
This plant prefers some protection from the summer sun and grows well in the shade of trees.
It is a cold-hardy plant and can tolerate at least -20 ° C.
It has a somewhat invasive tuberous root system that can colonize sparse woody systems and can be grown as a grass to be cut every year in autumn.
Propagation can take place by seed both in open fields and in cold greenhouses.
The seed usually germinates in 10 – 20 days at 20 ° C.
When the seedlings are large enough to handle, they can be transplanted into individual pots and grown in the greenhouse for their first winter. They should then be planted in their permanent positions in late spring or early summer, after the last expected frosts.
It can also propagate by division of the tufts in the autumn period.

Customs and Traditions –
Doronicum pardalianches, especially in the past, was commonly cultivated as a medicinal plant.
All the species of the genus Doronicum possess medicinal principles still considered valid but the medicinal uses are however reserved in particular to this plant.
The rhizome contains inulin, an ethereal oil, a bitter substance, traces of resin and mineral salts. The preparations are used as antispasmodics, astringents, sedatives, tonics and vulneraries.
According to folk medicine, the root of this plant has cardiotonic and nervine properties.
In particular, it is used for the treatment of nervous depressions. Due to its vulnerable properties it is indicated as a treatment in case of scorpion stings.
This plant, for a long time, was considered a poisonous species. Jacopo Antonio Cortusi, director of the Botanical Garden of Padua in the first half of the 1600s, assured him that he had seen a dog die in a few hours after having ingested the plant. Moreover, the same specific name would refer to these poisonous characteristics. Many other botanists, including Linnaeus himself, doubted its poisonous potential, which was later completely denied.

Preparation Method –
Leopard’s-bane was used, especially in the past, in folk medicine, for its alleged cardiotonic and nervine characteristics. Both the whole plant and the rhizomes are used.
