10 Seeds Sweet Black Eyed Susan Rudbeckia subtomentosa Hardy Perennial Flower

Sweet Black Eyed Susan is a hardy perennial wildflower known for its bright golden-yellow petals surrounding a dark, cone-shaped center. Blooming from mid-summer into early fall, it brings long-lasting color and a cheerful, meadow-style presence to gardens and naturalized areas, and its tall stems make it a fine choice for mixed borders and cut flower arrangements. This species is valued for its easygoing nature and its ability to return year after year in the right conditions.
Sweet Black Eyed Susan works well in cottage gardens, pollinator-friendly plantings, and wildflower meadows, where its nectar-rich blooms draw in bees and butterflies through the warm season. It pairs nicely with ornamental grasses, coneflowers, and other perennials for a layered, informal look, and the sturdy stems hold up well when cut for indoor bouquets. Plants prefer full sun and well-drained soil, tolerating heat and periods of dryness once established.
