About Rudbeckia
Also known as Black-Eyed Susan, Rudbeckia is a cheerful and hardy perennial known for its vivid yellow flowers with contrasting dark centres. Blooming from mid-summer well into fall, this plant thrives in both garden beds and containers, bringing long-lasting colour and structure to your space. It is a great choice for low-maintenance landscapes and pollinator gardens, attracting bees and butterflies throughout the blooming season.
