If you're looking for variations on a classic cottage garden vibe, look no further. Rudbeckia, commonly known as Black Eyed Susan, from the family Asteraceae is a perennial that is often treated like an annual. The genus is Rudbeckia and the species is hirta or tribola. These prolific flowers are fairly easy to grow and come in a variety of colors beyond the classic yellow and black center pairing. You can easily find them in hazy purple, dark cherry, and burnt orange palettes with long petals around their namesake center “face”. R. hirta are often treated as an annual, but do perennialize in mild zones. R. triloba is a true perennial in warmer zones and a biennial in the coldest zones. While Rudbeckia prefers full sun and long days, it will thrive in a range of temperatures 25 - 90 Degrees Fahrenheit, allowing for it to be successful across many zones.
