Eremurus /ˌɛrɪˈmjʊərəs/[2] is a genus of deciduous perennial flowers in the family Asphodelaceae. They are also known as the foxtail lilies or desert candles. They are native to eastern Europe in (Russia and Ukraine ), and temperate Asia from Turkey to China , with many species in Central Asia.[1][3]
The inflorescence consists of a tall floral spike whose individual flowers extend their anthers around the stem axis as in the bottle brushes. Depending on the species, the spike consists of many densely-arranged, small flowers in shades of orange, yellow, white, pale pink or red-orange. The grey-green, straplike leaves grow in a tuft from the succulent root crown. Eremurus is known for its thick, fingerlike roots, which grow from a central growth point. The blooming spike is notably tall and relatively narrow, rising from 3 to 9 or 10 feet above the foliage, depending on the species. These plants are mainly native to western and Central Asia, although Eremurus thiodanthus is endemic to the Crimea.[4]

Cultivation
Eremurus is hardy to USDA Zones 5–7. Usually four species are available commercially for cultivation:
- E. himalaicus grows to about 4 ft (1.2 m) with pure white racemes
- E. robustus can reach 8–10 ft (2.4–3.0 m) in height with pink or white flower spikes
- E. stenophyllus, a dwarf species, reaches 2–3 ft (0.61–0.91 m) in height with yellow flowers.
Also E. × isabellinus which is a hybrid of E. olgae and E. stenophyllus is available as 'Cleopatra', with orange spikes.[6]
The cultivar 'Joanna' has won the Royal Horticultural Society's Award of Garden Merit.[7]
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.[8][9]
