The Story

Plant Bio

Eutrochium maculatum, spotted Joe Pye weed, is a stately clumping perennial native to eastern North America, reaching four to seven feet. Flat-topped clusters of dusky pink to purple florets open from midsummer into October, carried on stout purple-spotted stems. Sharply toothed leaves are held in whorls of four or five, which is the easiest way to recognise the genus.

The flat-topped inflorescence distinguishes it from the domed heads of its relatives, and the solidly purple or purple-spotted stem is diagnostic. It is one of the heaviest late-summer butterfly plants available, and unlike most tall perennials it holds itself upright without staking as long as it has moisture.

Uses & Benefits:

Large flat heads of dusky pink over purple-spotted stems, at the back of a border from July to October.

Thrives in wet ground where most tall perennials fail, and stands without staking.

One of the heaviest nectar sources for late-summer butterflies and honeybees; seed heads feed birds.

Planting

How to Grow

Plant in spring in moist to wet, fertile soil.
Choose full sun to partial shade.
Allow three to four feet of width per clump.
Keep the soil consistently moist through summer.
Cut back by a third in late spring for a shorter plant.
Divide every three or four years.

Pro Tip

Cut it back by a third in late May if seven feet is too much — it flowers a little later but stands up on its own.
