Eupatorium serotinum (Late Boneset)
Also known as Late-flowering Thoroughwort, White Boneset, Late-flowering Boneset.
Late Boneset is a clumping perennial featuring small white flowers grouped into larger flower heads. It is a must-have in a pollinator garden. It prefers soil on the moister side in part sun to part shade. The sunnier the location the more moisture it will need. It is an important late season nectar source. Its flowers attract butterflies, native bees, pollinating flies, wasps and beetles. It is a host plant for several moth species. Seeds are a food source for seed-eating birds.
Late Boneset works well in cottage, meadow or prairie gardens, rain gardens and naturalized areas.
