Hivernage

Leave the dried flower heads standing through the winter to provide food for birds and interest in the garden. Cut the stems back to the ground in early spring before new growth begins.

En pot

They grow well in large containers, provided the pot is at least 30 centimeters deep to accommodate their taproot.

Group these with other sun loving prairie natives to create a low maintenance ecosystem that supports local pollinators.

• Bee Balm — Both plants are magnets for butterflies and bees in a sunny border.

Espèces similaires

Ce qu'on demande souvent

Do I need to deadhead my coneflowers?

Deadheading can encourage a second flush of blooms, but leaving them on provides winter food for goldfinches.

Why are my coneflowers drooping?

They often droop during the hottest part of the day as a natural response to heat, but they should perk up by evening.

D'où vient le nom

The genus name Echinacea is derived from the Greek word for hedgehog, describing the prickly cone, while purpurea refers to the purple color of the petals.

Bon à savoir

• The name comes from the Greek word echinos, meaning hedgehog, referring to the spiky center.
• Native Americans used the roots to treat snakebites and various infections.
