Maintenance

Low maintenance. Spreads by rhizomes so give lots of room, Roots are shallow and is easy to pull out if thinning is needed to fit garden space. Good as a border plant or groundcover. Prefers woodland margins, stream banks, wet meadows, ditches. Tolerates poor drainage. Can grow in full sunlight with extra water, but does better with shade in the late afternoon. Propagation: Seed, Root division.

Comments

Blooms July-November. Fluffy-edged light blue flowers, at the end of stems, forming an almost flat top. Leaves are somewhat triangular with a bluntly toothed edge. Especially attractive to butterflies, bees and birds in the Fall.
Previous Scientific Name(s): Eupatorium coelestinum
