The yellow coneflower (Rudbeckia) is bee-friendly, hardy and relatively easy to care for. The perennial delights with golden yellow flowers from August to October.
The yellow coneflower (Rudbeckia fulgida var. sullivantii) has become one of the most popular native perennial plants. Similar to a small sunflower, the yellow ray flowers with their dark brown center appear and delight the eye well into October. The easy-care perennial also attracts bees and butterflies. The coneflower (Rudbeckia) can be combined in a variety of ways in the bed and is a popular cut flower.Yellow Sun Hat - Origin
The plant presented here has made a name for itself as one of the best-known representatives of the coneflower genus. The original home of the daisy family is in North America. The hardy perennials are found between Michigan and Missouri as well as extending south to Alabama and Arkansas.

Plant yellow coneflowers
Find the right location
So that the yellow coneflower can unfold its full bloom, choose a sunny and warm location. The plant is particularly beautiful in group plantings in natural or perennial gardens. Suitable bed neighbors are goldenrod, pampas grass or asters.
➔ Choosing the ideal substrate
So that the yellow coneflower grows well and impresses with its lush flowering, fresh and well-drained soil is an advantage. A nutrient-rich and moist soil suits the plant well. A slightly acidic to alkaline substrate is tolerated.
» Tip: The soil must not be too moist or dry out.
When the soil isIntuition required. The soil must be able to store moisture well. Since this is not the case in loose sandy soil, potting soil is mixed into the substrate.

- Water the plant well
- Mulch plant
The yellow coneflower can be planted all year round. The only requirement is that the ground is not frozen. Planting in spring or early summer creates the best basis for growth. Then the ground is damp and has already warmed up.
Stones, roots and weeds are removed from the soil. Heavy clay soils tend to compact and should be made more permeable with sand or gravel. Once the perennial has been planted, it is supplied with plenty of water. Applying a thin layer of mulch is a good way to keep the moisture in the ground longer instead of evaporating unused.
Yellow Coneflower - care
Watering the yellow coneflower properly
After planting, the yellow coneflower must be kept sufficiently moist. In dry summers it must therefore be watered several times a week. If the perennial has grown well, water less.
The plants get enough water. Only when the soil has dried is watered again. Small watering amounts are not advisable, as the water should penetrate to the roots.
» Tip: Wilted leaves indicate a lack of water.
If the yellow coneflower is cultivated in a bucket, it must be watered regularly. Since waterlogging is not allowed, the planter must have sufficient drainage holes. The water must not accumulate in the coaster. Drainage made of gravel or broken pottery prevents waterlogging in potted plants.
➔ Fertilize the purple coneflower properly
The yellow coneflower needs a nutrient-rich soil. When planting, compost can be added as a long-term fertilizer. Annually before sprouting, fertilize with a conventional fertilizer for flowering plants. Fertilize again in early summer to promote growth and flowering.
» Tip: If the coneflower has light green leaves, the plant is not getting enough nutrients.
From August the fertilization will be stopped. If too much nitrogen gets into the soil, the plant loses its frost tolerance.
➔ Cut Yellow Coneflower
The plant can be cut back after flowering in late autumn. The infructescences are a source of food for the birds in winter and offer a bizarre sight in the conservatory. The plant suffers no disadvantages if the inflorescences are only cut back in spring.
Propagating yellow coneflowers
The Yellow Coneflower can be propagated by seed. Since the plants belong to the cold germs, the process is a bit more complex. Only when the seeds have been exposed to a cold stimulus are they stimulated to germinate. Therefore, the yellow coneflower seeds are stored in the refrigerator for a few weeks before sowing.
Older plants can be divided. This is easily possible after four to five years in the bed. For this purpose, the plant is taken out of the ground in spring and divided with a sharp spade. The newly acquired plants are immediately replanted. Not only can new plants be obtained in this way, the mother plant also remains vital and vigorous.
Diseases and pests on yellow coneflowers
The yellow coneflower is particularly robust and no typical plant diseases are known. Very few plants tolerate waterlogging. Incorrect watering behavior can also be fatal for the Rudbeckia.
Typical signs of damage are a rarity on yellow coneflowers. The plant is not susceptible to powdery mildew, nor are slugs attacking the leaves and stems.
Winter coneflowers
The plant is hardy. For younger specimens, a layer of leaves or twigs can protect against frost damage. Potted plants must also be watered in winter. The plant pot is given winter protection from garden fleece, but can be left outside.
