Common Ironweed

Common ironweed is a tough, adaptable native perennial found naturally in moist prairies, roadsides, and streambank edges across the central and eastern United States — its compact size (3–5 feet) compared to tall ironweed makes it more useful in typical garden settings while delivering the same brilliant purple pollinator impact. Dense, flat-topped clusters of vivid purple flowers open from midsummer into fall, overlapping with many other prairie perennials and providing critical late-season nectar for migrating monarchs, swallowtails, and native bumblebees. Plants spread slowly by rhizomes and self-seeding, eventually forming clumps that can be divided every 3–4 years to maintain vigor and share plants. Combine with yellow-flowered natives like sneezeweed, black-eyed Susan, and prairie coneflower for maximum visual impact — the complementary warm yellow and cool purple combination is a classic of native meadow plantings. Спосіб посадки: Посів у відкритий ґрунт Відстань між рослинами: 18–36 дюймів Висота: 36–72 дюймів Дні до схожості: 14–30 Температура ґрунту для схожості: 18–24°C
