Tansy is a hardy perennial wildflower admired for its clusters of bright golden-yellow, button-like blooms and finely divided, fern-like foliage. Flowering from mid to late summer, it adds cheerful color and texture to cottage gardens, wildflower borders, and natural landscapes. Native to Europe and Asia, tansy thrives in full sun with well-drained soil. It is drought-tolerant once established and attracts beneficial pollinators such as bees and butterflies. Historically, tansy was valued in traditional herbal practices and as a natural insect repellent due to its strong aromatic leaves.
