Faits intéressants
Cut-leaved Coneflower can become an impressive plant in a garden. Its deeply divided leaves give it its common name.
Cut-leaved Coneflower is one of the larger native members of the sunflower family and can tower over many garden perennials.
The dried flower heads can remain attractive into winter, especially when left standing. This is a vigorous spreader. Give it plenty of room or plant it where its natural spreading habit is desirable.
