Joe Pye weed

Eutrochium purpureumAsteraceaeHerbaceous perennial

A tall North American perennial with domed heads of dusty pink flowers in late summer, and one of the best late-season plants for bees and butterflies in a large border. It is the American counterpart of hemp agrimony and considerably more architectural.

Value to bees

Pollen

As a honey crop
Minor honey crop — a surplus only locally or occasionally
Which bees, and why
The broad domed heads of shallow florets are accessible to almost everything, and a plant in full flower is loud with bees, butterflies and hoverflies simultaneously. It is a mainstay of North American pollinator planting.

Domed heads of tiny shallow florets forming a broad landing platform.

Worth knowing
An outstanding late-season nectar and pollen source, and one of the most heavily visited plants in a late border.

Flowering

In flower
July to September (northern hemisphere)

A late summer flow, running into early autumn.

Growing it

Conditions
Sun or light shade on moist to damp soil. It tolerates ordinary border soil that does not dry out and thrives in genuinely damp ground.
Size
1.5-2.5 m tall.
Native range
Eastern and central North America, in damp meadow, woodland edge and streamside.
Suits
Large gardens, Meadow or wildflower area
  • Too tall for a small border; the compact cultivars are the practical option.
  • Cut back in late winter rather than autumn, leaving the stems for overwintering invertebrates.
  • Needs moisture — it wilts and disappoints in a dry summer border.

What it looks like

A very tall upright perennial with whorled lance-shaped leaves and large domed heads of fluffy dusty-pink to mauve florets, held well above head height on strong stems.
