This North American genus belonging to the daisy family (Asteraceae) consists of 15 species of perennials. It is very popular in gardens because of the plant's great hardiness, ease of cultivation, and valuable late season flowering. Most are fairly bulky plants, with branched or unbranched stems, and often have lance-shaped deeply veined leaves. From late summer they carry masses of large golden yellow daisies, usually with dark brown to black disc florets. Dwarf, double-flowered, and variously colored forms are available. They flower until cut back by frost. Rudbeckia was named by Linnaeus for a professor at the University of Uppsala, Olaus Rudbeck (1650-1740), who employed the young Linnaeus as a tutor for his children, of which he had 24!
CULTIVATION
Plant in a sunny open position with moist well-drained soil. Deadhead or use as a cut flower to encourage continued blooming. Mildew can occur but usually only late in the season. Propagate by division, from basal cuttings, or from seed.
Top Tip
Because Rudbeckia plants bloom late in summer, they bring welcome color to borders and beds when the blooms of other plants have faded.
