White snakeroot
Ageratina altissima
Родина: Asteraceae • Рід: Ageratina
БагаторічнаСередньоДекоративна
Surface sow seed or plant divisions in moist, humus-rich soil in partial to full shade; white snakeroot fills a critical niche as a shade-tolerant late-season bloomer, producing clouds of white fluffy flowers from August through October when pollinators most need late-season forage in shaded areas.

Surface sow seed or plant divisions in moist, humus-rich soil in partial to full shade; white snakeroot fills a critical niche as a shade-tolerant late-season bloomer, producing clouds of white fluffy flowers from August through October when pollinators most need late-season forage in shaded areas. It naturalizes freely by self-seeding under trees where few other plants bloom in fall. Note that all parts of the plant are toxic to livestock and humans — the toxin tremetol accumulates in milk of cows that graze on it, historically causing 'milk sickness' in settlers. Do not plant near pastures or where children might graze on it; it is safe as an ornamental in a garden setting.
Спосіб посадки: Посів у відкритий ґрунт
Відстань між рослинами: 18–24 дюймів
Висота: 24–48 дюймів
Дні до схожості: 14–21
Температура ґрунту для схожості: 18–24°C

Час посадки: -2–2 тижнів від останнього весняного заморозка
Surface sow seed in spring in partial to full shade; plants establish readily and self-sow to naturalize. Not appropriate near livestock — the plant's toxins pass through cow's milk and historically caused 'milk sickness'.
