Thin-leaf coneflower

Press seeds onto moist soil surface or cover very lightly; they need light to germinate and germinate readily in 7–14 days. Unlike Rudbeckia hirta, R. triloba is a true biennial-to-short-lived-perennial that produces abundant small golden-yellow flowers with a dark center from midsummer through hard frost. Plant in full sun to partial shade in average garden soil; plants self-sow prolifically and naturalize easily in meadow and prairie plantings. Deadhead some stems to extend the season and let others set seed to perpetuate the colony. Спосіб посадки: Посів у відкритий ґрунт Відстань між рослинами: 18–24 дюймів Висота: 24–60 дюймів Дні до схожості: 7–14 Температура ґрунту для схожості: 18–24°C
