Rudbeckia or Coneflower is an herbaceous perennial plant that can reach up to a meter in height. It produces beautiful flowers resembling daisies. The plant also possesses anti-allergic and anti-inflammatory properties, offering relief from colds, flu, runny noses, and coughs.

Coneflower Plant

Rudbeckia, known by its Latin name Echinacea (Echinacea purpurea L.), is characterized by its central head filled with thorns. The name is derived from the Greek ‘Echinos,’ meaning ‘hedgehog.’ ‘Purpurea’ denotes the flower petals’ inherent color in Latin. The Sun Hat was first recorded in Europe at the beginning of the twentieth century, although it originally hails from North America. Indigenous tribes of this continent have used the plant for centuries to heal arrow wounds, snake bites, and injuries.

It’s well-regarded as a disinfectant for abscesses, boils, superficial wounds, and burns. For medicinal purposes, every part of the plant can be utilised, including flowers, stems, leaves, or the entire plant with attached roots.

The name ‘coneflower’ is used for two plant species, Echinacea and Rudbeckia. Both plants closely resemble each other and belong to the same family. Originally, Echinacea has purple and pink flowers, while Rudbeckia exhibits more yellow, orange, and red tones. The most noticeable difference lies in the flower’s size; Rudbeckia’s flowers are generally smaller with fewer petals compared to Echinacea.

Sowing Coneflower

Seeds Rudbeckia is a short-lived plant that propagates through seeds, providing continuous delight as they easily generate copious amounts of seeds. Seed formation occurs from winter to spring. Note that newer varieties rarely produce seeds. Simply place seeds on the surface of moist soil, covering them with a thin layer of sifted sand or sawdust.

You can also sow in pots or other planters. Seeds germinate within 2 to 3 weeks at a consistent temperature of 15-16 º Celsius. Transplant them when they reach a height of 5 to 10 cm. Rudbeckia fulgida propagates easily through seeds and can be sown in the northern hemisphere during mild winters from December to April.

Planting Coneflowers

Rudbeckia thrives in sunlight but can tolerate partial shade. It flourishes in moderate climates and withstands mild frost. It requires ample moisture but cannot endure waterlogging, so it needs to be planted in moist, well-draining soil.

Adaptable to various soil types, Coneflowers excel in soils with a pH between 6.0 and 7.0. Once established, they can withstand dry periods. The plant may wither with the onset of the first frost, but it blooms again the following season. During winter, protecting the roots with mulch is advisable against the cold.

Pruning Coneflowers

It’s highly recommended to prune the plant in late autumn, allowing it to germinate in spring. Remove the dried flowers to maintain its beauty and extend blooming. However, avoid excessive pruning as Rudbeckia dislikes disturbance. Prune moderately by cutting a few stems from each stem group, preferably the oldest or largest, allowing younger stems to grow. Fertilise the plants once a year, preferably in spring.
