Rudbeckia hirta
Hairy rudbeckia, yellow daisy, black-eyed Susan: this last name, translated from the English Black-eyed Susan, comes from the contrast between its golden-yellow petals and its raised brown-black center. The genus is named after Olof Rudbeck, a Swedish botanist and Linnaeus’s mentor, who was honored in this way.
Characteristics:
-
Generous flowering: large, bright-yellow daisies with a nearly black-brown center, from summer until the first frosts.
-
Very easy to grow: ideal for beginners, it requires little maintenance and tolerates variable conditions.
-
Excellent cut flower: remarkable vase life, lasting more than a week.
Sowing advice:
-
Exposure: sunny, essential for abundant flowering.
-
Soil: truly any type, even poor and stony, as long as it is well drained. It tolerates drought once established and mainly dislikes stagnant moisture in winter. No fertilization is needed.
-
Method: sow in spring, in pots under cover from March or directly in the ground after the last frosts, on the surface without covering: the seeds need light to germinate. See how to sow your seeds.
Care advice:
- Water regularly during dry periods in the first year. Remove faded flowers to extend flowering into autumn.
- Do not cut everything back in autumn: leave a few dried centers standing for wildlife and winter structure.
Beneficial combinations:
Benefits for biodiversity:
- Its broad, flat flower head provides an ideal landing strip: bees, hoverflies, and butterflies flock to it all summer.
- Its centers, left standing in winter, feed goldfinches and tits, which come to collect the seeds.
Uses:
- Beds, shrub borders, beside walls, or flower meadows. Excellent in summer bouquets.
Harvesting your own seeds:
Leave the centers to turn brown and dry completely on the plant, then crumble them over a container to release the small black seeds. Rudbeckia also readily self-seeds in the garden. See how to store your seeds.
