Rudbeckia hirta

rud-BEK-ee-ah HER-tuh

Rudbeckia hirta L. is the correct and accepted scientific name for this species of Rudbeckia. It was described by Carl von Linnaeus in Species Plantarum in 1753. The 2013 version of The Plant List names 3 accepted infraspecific names (varieties) of Rudbeckia hirta.

Plants of the World Online by Kew launched in 2017 is still uploading data and as of 3-13-18, when I am making this page, it lists no information for this species. In fact, it doesn’t list any accepted species on the Rudbeckia page and the World Checklist of Selected Plant Families, also by Kew, doesn’t even list the genus at all. The 2013 version of The Plant List names 25 accepted species and another 15 accepted infraspecific names. It also lists a total of 75 synonyms and 78 unresolved names. The Plant List is no longer maintained.

We have A LOT of Black-Eyed Susan on the farm and you can see them just about anywhere they are allowed to grow. They are a Missouri native wildflower and the USDA Plant database shows they are native everywhere in the US except Arizona and Nevada. They are also native to most of Canada. I wonder how they skipped Arizona and New Mexico. Rudbeckia hirta is the state flower of Maryland.

Whenever I see any of these plants in the garden or flower beds I just let them grow. Never hurts to have a few pollinators here and there for bees and butterflies.

Rudbeckia hirta is very self-seeding so deadheading when they are in your flower beds may be a good idea. There are many popular cultivars of Rudbeckia fulgida and I grew three in 2017.

Various Native American tribes used Rudbeckia hirta as an herbal remedy for colds, flu, infections, swelling, and snakebite. Apparently, all parts of this plant are NOT edible, though.

I will continue to add more photos and information as time goes by. I am sure they aren’t going anywhere soon. 🙂
