Family: Asphodelaceae
Citron day-lily is a flowering, herbaceous plant. Arising from a bulbous clump are blade-shaped leaves and a solitary (sometimes double), trumpet-shaped, yellow flower. The showy flowers are open for one, maybe 2, days only. The botanical name comes from the Greek words hemera, meaning day, and kallos, meaning beauty; this beauty lasts only one day. The common name is misleading, as this plant is not a lily. Native to China, it blooms in the summertime.
The citron day-lily is not prone to pests. A low-maintenance plant, it is drought tolerant and tolerant of poor soil. For vigorous growth, separate the clumping bulbs every few years. This species will naturalize in the garden.
