Black-Eyed Susan

Not only does black-eyed Susan have a name you can’t forget, it also has a bright yellow, dark-centered flower you can’t mistake. These herbaceous wildflowers grow all over North America, from yards and gardens to fields, prairies and mountains.

Black-eyed Susan’s scientific name is Rudbeckia hirta. It belongs to the Asteraceae family, more commonly known as the aster or daisy family, which includes a whopping 32,000-plus species. Black-eyed Susans planted in full to partial sun grow quickly and with little intervention, making them a popular pick for beginners and casual gardeners. Their only preference in soil is that it is well-drained. Follow these simple guidelines, and you’re bound to have a burst of yellow – not just next summer, but also the following summer, thanks to black-eyed Susan’s perennial nature.
