Eremurus × isabellinus is a hybrid of garden origin, derived from the crossing of E. stenophyllus with E. olgae. The first crossing was made by Sir Michael Foster at Great Shelford, [2] England, at the end of the 19th century, and replicated in France by the Vilmorin nursery at Verrières-le-Buisson in 1902. The name of the hybrid is derived from the isabelline colour of the original F1 hybrid flowers.[1] The genus is often known by the common names foxtail lily and desert candle.

Description

Eremurus × isabellinus produces stems 1.5 m high terminating in bottlebrush-like inflorescences in June and July. The narrow strap-like leaves form a mound of bluish green foliage at the base, which begins to die off as the plant flowers.[2]

Cultivation

Eremurus × isabellinus is fully hardy, and best grown in full sun in a fertile, sandy, well-drained soil; it tolerates alkaline conditions.[2] The hybrid has given rise to around 20 cultivars,[3] assembled into groups defined by origin: Shelfordi and Ruiter are the oldest; more recently, Amand, Highdown, and Erfo.
