How to Grow Eremurus — Foxtail Lily

Eremurus Foxtail lily

Eremurus–commonly called foxtail lily–produces tall slim spirelike spikes of white, pink, or yellow blooms that look most dramatic when planted in groups. Flowers cover upper half stems to 8-feet tall.

Eremurus belong to the lily family and like other lilies, it requires a cold winter to bloom. Blooms appear in very early spring and can be damaged by late frosts; plants should be protected by plant blankets or large cardboard boxes until hard frosts are past.

Use Eremurs at the back of perennial borders and plant them in drifts to emphasize their bold, linear lines. They are dramatic set against an evergreen background.

The stems of this tall perennial may need staking.
