Find helpful answers about Hemerocallis citrina Baroni seeds, flowering characteristics, and daylily cultivation.
Hemerocallis citrina Baroni is especially admired for its lemon-yellow, fragrant flowers and distinctive evening flowering habit. Unlike many daylily varieties that open during the daytime, its flowers generally begin opening in the afternoon or evening and remain open into the following day. Its graceful foliage also provides ornamental interest throughout the growing season.
Yes. Hemerocallis citrina is known for its nocturnal flowering habit. Its large, trumpet-shaped yellow flowers typically begin opening during the afternoon or near sunset and remain open through much of the night. The blooms are pleasantly fragrant, making this daylily particularly attractive for gardens enjoyed during the evening.
Germination and flowering times depend on seed freshness, growing conditions, and plant development. Seed-grown daylilies generally require more time to reach flowering maturity than established divisions. Under suitable conditions, allow approximately 2–5 years for the plant to develop toward flowering maturity. Provide adequate sunlight, fertile soil, and consistent moisture to support healthy growth.
