Is Black Eyed Susan Child Safe?
Thunbergia alata is safe to grow around small children.
The Rudbeckias might not be. They are toxic to cats and dogs. I was not able to find any toxicity information specific to children but I would keep all plants in the Rudbeckia family away from both kids and pets just to be safe.
Black Eyed Susan Perennials
Rudbeckia fulgida, the perennial Black Eyed Susan is one of the most popular perennials in the U.S. for good reason. It is not picky about soil. It loves the sun and will tolerate heat and humidity. It blooms profusely from mid-summer to fall.
Rudbeckia Goldsturm (sometimes misspelled Rudbeckia Goldstrum) is the most popular black eyed Susan perennial growing in the U.S. today.
Rudbeckia hirta Gloriosa
This variety is actually a biennial or short-lived perennial that is often grown as an annual because it blooms the first year from seed.
Gloriosas are treasured for their 6 inch daisy flowers which feature dark brown centers. The bases of the petals are orange to mahogany. The tips are gold or lighter orange. The blooms may be single or double in form.
These spectacular flowers top sturdy, erect, 3 foot stems. They make excellent cut flowers and cutting the blooms causes the plant to produce more flowers.
They will reseed themselves if the flowers are not cut.
