Details
A stalwart of any wildflower meadow, Black-Eyed Susan is perhaps the most emblematic of the classic North American Wildflowers. This flower is extremely resilient, and though it clearly prefers sun, our trials have consistently demonstrated that it can tolerate partial shade as well. Native to the eastern United States, it has been largely naturalized throughout the rest of the country.
