Doronicum

The genus Doronicum includes 35 species of herbaceous rhizomatous perennial resistant plants. Many species are used as flowers for cutting. They are characterized by large single baskets of yellow flowers, resembling chamomile. Doronicum austriacum (Doronicum austriacum) - a species up to 1 m tall, with ovate-heart-shaped toothed leaves and flowers blooming in spring, collected in baskets up to 7 cm in diameter. Doronicum caucasicum (D. caucasicum) up to 1 m high. The stem is erect, the basal leaves are broadly ovate, whole-edged or toothed, emerging from the buds in late summer, the stem leaves are sessile alternate. Flowers collected in baskets up to 8 cm in diameter, on a long peduncle, bloom in spring. Doronicum cordata (D. cordatum, or D. columnea) is a species up to 25-30 cm tall with a short rhizome and heart-shaped leaves on long petioles. Flowers collected in baskets with a diameter of 5 cm, bloom in spring. From crossing this species with Doronicum Austrianum, the hybrid 'Miss Mason' was obtained. Doronicum glaciale (D. glaciale) - a species up to 20 cm tall, with oval or lanceolate leaves. Flowers collected in baskets with a diameter of 4.5 cm, bloom in spring. Doronicum grandiflorum - pubescent species up to 35 cm high. Flowers in baskets with a diameter of 6.5 cm bloom in spring. Doronicum plantain (D. plantagineum) is characterized by oval-elliptical leaves that taper into a long petiole.

Cultivation

Doronicum is grown in the open ground in group plantings on lawns, flower beds, in mixborders, as flowers for cutting. They are planted permanently in spring (in wet ground) or in October, while organic fertilizers are applied at the same time. Plants are planted at a distance of 20-30 cm from each other (low-growing species and varieties) or 30-40 cm (taller and more lush). If the land is not very fertile, then in late spring, mineral phosphorus-potassium fertilizers are added 2-3 times to the water for irrigation in the amount of 10-20 g per bucket.

Location

It is advisable to plant doronicum in the open sun, if possible in a place protected from the wind (it damages the peduncles in tall species); they also tolerate partial shade well.

Temperature

Doronicums are resistant to both high and low air temperatures. Only in the first year of life, young plants should be protected from frost by mulching the soil with leaves, peat and other organic materials.

Watering

During active vegetative growth and development, water abundantly to constantly keep the soil moist, and stop watering in autumn and winter.

Care

Remove damaged parts and discolored baskets to encourage the formation of new ones.

Reproduction

Propagated most often by dividing rhizomes every 2-3 years and seeds. Sowing is carried out in spring or autumn in boxes with soil consisting of 1/3 of fertile land and 2/3 of peat, with the addition of a small amount of sand. Also apply the division of the bush, immediately planting the resulting parts finally in the ground.

Diseases

The leaves and stems can be covered with oidium, a superficial white mold that causes the plant to weaken. It is easy to get rid of it by treating it with sulfur or special fungicides.

Acquisition

Seeds and plants in cups for transplanting can be purchased in spring in gardening centers, flower shops and nurseries. Check that the seeds are fresh, this guarantees germination. Choose compact and blooming seedlings.
