Giant desert candle’s botanical name comes from the Greek words eremos — solitary and oura — tail, a reference to the plant's flower spike which towers above its long, narrow foliage. The roots originate from a rhizome with the roots extending from a central crown, which must be handled with care when planting because the roots can be brittle. From May to August, giant desert candle produces a spectacular spike of white flowers on 6- to 10-foot stems above bright green leaves up to 4 inches wide and 48 inches long. Plant foxtail lily in full sun, and protect it from strong winds. It is very cold hardy and flowers best when grown in cold climates.
