Eremurus are tuberous roots which are hardy down to zone 5. Plant eremurus perennial roots 6 inches deep, 12-15" apart in full sun and fertile, well-drained soil. Sandy soil enriched with compost is ideal, however, eremurus grows well in a wide range of soil types provided the drainage is good. Good drainage is especially important in the winter time.

     The tuberous roots of eremurus (which resemble a starfish) are brittle, so handle them carefully. Dig a wide, shallow hole and plant with the pointed bud in the center facing up. In a windy site, the stems of tall varieties may need staking. If, after several years, plants become crowded, lift the roots carefully in fall with a lifting fork and carefully separate them and replant.

     For winter protection of eremurus bulbs, provide protection in the fall, such as leaves or grass clippings up to 1 foot thick.

     Prior to planting, eremurus bulbs may appear spongy and somewhat discolored. This is normal and is not an indication of unthriftiness.
