Teasel is a striking biennial wildflower recognized for its tall, sturdy stems and distinctive spiky flower heads that bloom with tiny lavender-to-pale purple flowers arranged in concentric rings. Flowering from mid-summer to early autumn, it creates dramatic vertical interest in meadows, cottage gardens, and wildlife landscapes. It thrives in USDA hardiness zones 3-8, preferring full sun and well-drained soil. These nectar-rich blooms attract bees, butterflies, and other pollinators, while the dried seed heads provide an important food source for birds, especially goldfinches, during winter.
