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]

Species

As of November 2023, Plants of the World Online accepted the following species: [1]

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]
