Rudbeckia 'Goldstum'

Rudbeckia fulgida var. sullivantii 'Goldsturm'

Rudbeckia 'Goldstum' is a perennial herbaceous plant belonging to the Asteraceae family that blooms with bright yellow flowers from summer to autumn. In terms of growth characteristics, it thrives in well-drained soil and prefers sunlight. It is relatively cold-hardy and tolerates drought and heat well.

Propagation is primarily done by seeds and root division. For seed propagation, sow in spring or autumn. Early spring or autumn is the optimal time for root division, which involves dividing the roots of a mature plant into several parts for planting.

For cultivation, select a sunny location and plant in well-drained soil. Water moderately, avoiding overwatering, and provide adequate nutrients during the growing season. In particular, it is recommended to water thoroughly about 1 to 2 times a week during the summer.

It is widely used as an ornamental plant in gardens, especially as a background plant to create a spectacular landscape in harmony with other flowers. It is also popular as a cut flower and is used in flower arrangements.

Major pests and diseases include leaf-related conditions such as powdery mildew and rust, which manifest as symptoms of leaves turning yellow or drying out. Control methods include removing diseased leaves and ensuring good ventilation. Use appropriate fungicides if necessary. Aphids may occur as pests and can be controlled using soapy water or insecticides.
