Citron daylily is a vigorous, fragrant perennial known for its long, pale-yellow, night-blooming flowers that emit a sweet lemon scent in the evening. It thrives in average garden soil with regular watering and benefits from partial shade during the hottest part of the day. Divide established clumps every three to five years to keep plants healthy and blooming freely.
