Rudbeckia hirta. At 30–100 cm (12–39″) tall, this North American native annual wildflower is immediately familiar, and conjures a sense of the heat of mid-summer. Dark brown cone centres are surrounded by pure yellow petals in flowers 5-8cm (2-3″) across. Black Eyed Susan is a common name shared by many plants, but this is the annual that is native to the northeastern United States. This plant has been used by a number of First Nations as a medicinal poultice to treat a number of infections, including cold and flu. You’ll love the bright look of this plant in mass plantings or in larger containers.

This annual Rudbeckia is commonly known as Black Eyed Susan, but also answers to such folksy names as Brown Betty, Brown Daisy, Brown Eyed Susan, Golden Jerusalem, Poor-land Daisy, Yellow Daisy, and Yellow Ox-Eye Daisy. This wonderful, fun flower comes in so many shapes, sizes and colours. It is so easy to plant and grow Rudbeckia seeds. Follow these simple instructions.

Rudbeckia hirta
Family: Asteraceae


Season & Zone
Exposure: Full sun
Zone: 2-10

Sow indoors 6-8 weeks before last frost (early to mid-February on the coast), or direct sow about 2 weeks before last frost (middle of March on the Coast). If starting indoors, provide bright light and maintain a soil temperature of 21-25°C (70-75°F). Expect germination in 5-21 days.

Sow seeds on the surface of the soil. Thin or transplant to stand 30cm (12″) apart. In hot summers, some afternoon shade is appreciated.

Top dress with a thin layer of well rotted manure once a year. Keep watered in hot weather, and deadhead regularly. Plants may self-sow, which should be encouraged.

    Mine took a while to come out while planted indoors. But eventually they came out and seem a little bit lazy. 3 out of 4 came out, so I am satisfied with the germination rate and happy I started them early as I want them out in April already. I would say bottom heat helped them to wake up.

    I would like to update that they are going really strong, especially since planted outdoors. One single plant in full sun gave incredible 4 main stems with about 5 flowers each just to begin with. They are truly warm season ladies. Compared to the ones I planted in part shade one plant on sun equals about 3 on part shade. Give them a good warm love and they will thrive. My bomber bees are hoving around.
