Lemon 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. Commonly called lemon day-lily, 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. An early bloomer when compared with other daylilies, flowering begins in May.
Native to Eastern Asia from Japan to Siberia, the lemon day-lily thrives in Hawaii. One cultivar ‘Nuuanu’’ flowers twice a year, spring and fall. The daylily is not prone to pests. A low maintenance plant, the day lily 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.
