An easy-to-grow member of the Aster Family. Best for naturalizing and not in a formal garden. Since it is a tall, dominating plant, it is best located at the back of the garden. Spreads quickly once established and can form sizeable colonies. Flower heads are 3 – 6 inches across. Large leaves give a tropical appearance to the plant. When winter weather brings ice, water seeps from the stems and freezes into fascinating ice sculptures, hence many of its common names. Native to moist forest edges, open woods, and on streambanks. Flowers are an exceptional nectar source for both butterflies and bees.
