Quand planter: autumn
Hivernage: Ensure the soil is well drained to prevent the roots from rotting during wet winters. A light mulch can be applied to protect the crown from extreme temperature fluctuations.
En pot: Not well suited for containers due to the extensive root system and extreme height.

Division

1. Carefully lift the root clump in late summer during dormancy.
2. Gently pull the fleshy roots apart ensuring each section has a growing point.
3. Replant immediately in well draining soil at the same depth as before.

Plant with low growing perennials that thrive in dry summer conditions to protect the dormant roots from excess moisture.

Bonnes associations

Peony — They share similar sun and soil requirements while providing contrasting foliage textures.
Nepeta faassenii — The low growing habit of catmint hides the base of the Eremurus as its leaves begin to fade.
