Additional Notes

A smaller version of Joe Pye Weed can be found in Eupatorium maculatum 'Gateway'. this form grows to about 4-6 feet tall and good for smaller spaces.

Very large flower heads in late summer that attract butterflies.

soils that retain some moisture provide the best conditions for best looking foliage.

May take 2-3 years for plant to reach maturity. Can prune back in June for shorter more compact plants.
