Rudbeckia fulgida var. sullivantii 'Goldsturm'
flowerGoldsturm is the benchmark black-eyed Susan, an award-winning selection of Rudbeckia fulgida var. sullivantii that blankets compact 2 ft clumps in golden-yellow daisies with dark chocolate centers from midsummer to fall. A tough, long-lived native perennial for zones 3 to 9 that anchors pollinator and cottage borders and returns reliably each year.

Fertilizer
Compost or balanced; low needs
Start seed indoors 8 to 10 weeks before the last frost, pressing it onto the surface since light aids germination, then transplant around the last frost date. Goldsturm thrives in full sun and average, well-drained soil and shrugs off clay, heat, and short droughts once established. Space plants 18 to 24 inches apart for the air circulation that wards off its main weakness, leaf-spot disease. Divide the clumps every few years to keep them vigorous.
🌼 Have a different variety?Cultivars of the same species usually share the same basic care — they differ mainly in flower color, height, and bloom form, not in how you grow them. So this guide still applies even if your exact variety isn't the one shown.

Site in full sun with good spacing and avoid wetting the foliage
Cut stems when the flowers have just fully opened and the centers are still tight for the longest vase life, about 6 to 10 days. Regular cutting and deadheading prolong bloom; leave the final flush of seed heads standing to feed goldfinches and to self-sow.
A pollinator powerhouse: the open daisy form feeds native bees, honeybees, and butterflies through late summer, and seed heads left standing feed goldfinches and other birds into winter. It is also a larval host for several butterfly and moth species.
