Опис

Sow stratified seed or transplant into deep, fertile, moist soil in full sun; the distinctive paired leaves wrap the square stem to form a cup that collects rainwater — providing a drinking and bathing site for birds. Tall yellow composite flowers bloom from midsummer through fall and are important sources of pollen and nectar for native bees, including specialist prairie bees. The large stature (6–10 feet) requires placement at the back of the border or in a wildflower meadow. Divide established clumps in spring every 4–5 years; the plant spreads by self-seeding in congenial conditions and can naturalize aggressively. Goldfinches harvest the seeds in fall. Спосіб посадки: Посів у відкритий ґрунт Відстань між рослинами: 24–36 дюймів Висота: 60–120 дюймів Дні до схожості: 14–28 Температура ґрунту для схожості: 16–21°C
