Eremurus


Eremurus is a genus of deciduous perennial flowers, also known as the foxtail lilies or desert candles. They are native to eastern Europe and temperate Asia from Turkey + Siberia to China.
The inflorescence looks similar to a long spike or a bottlebrush. It consists of many flowers in copper, bright yellow, snow white, pastel pink, orange or any combination of those colors. The leaves grow in tufts of thin, green, straplike strips. Species are known for thick roots that grow out from a central hub. It is also known for being tall, sometimes rising up to 10 feet over the foliage, depending on the variety. These plants are generally native to western and central Asia, although Eremurus thiodanthus is endemic to the Crimea.

Cultivation

Eremurus is hardy to USDA Zones 5-7. Usually four species are available commercially for cultivation:
Also E. × isabellinus which is a hybrid of E. olgae and E. stenophyllus is available as 'Cleopatra', with orange spikes.
The cultivar 'Joanna' has won the Royal Horticultural Society's Award of Garden Merit.
The octopus-like tuberous roots are easily injured; planting on a cone of soil, with the crown on the peak and the roots hanging down, is recommended. Plants are readily affected by winter root rot, so that a layer of sand or gravel beneath is recommended to ensure drainage. Covering with compost or mulch provides protection from frost.
