Rudbeckia Goldsturm is my favorite perennial if you do not count in Hosta! This wonderful plant starts to blossom in mid to late July and stays going well into September. We live in the middle of the woods and these plants receive as little as an hour or two of sunlight to 4 or 5. The plant located in the boulder wall receives the least amount of sun as it is on the northwest side of our house. They will spread but we haven’t found them invasive. The flower heads left into the winter create wintertime interest as well! This plant makes great cut flowers and are deer resistant. It was named the Plant of the Year in 1999 by the Perennial Plant Association of America.
