The “Gold Cup” daylily (Hemerocallis) is a highly popular, resilient perennial prized for its massive, vibrant, golden-yellow blooms. It thrives in full sun, requires minimal maintenance, and returns year after year to brighten up garden beds and borders. [1, 2, 3, 4, 5]
Plant Profile
- Bloom Color: Rich, “sunshine-yellow” with a slightly deeper golden throat.
- Height: Typically grows up to 30–48 inches (75–120 cm) tall.
- Foliage: Semi-evergreen to dormant, forming dense clumps of arching, grass-like leaves.
- Season: Produces an abundance of flowers from late spring through autumn, with recurring intervals of bloom. [1, 2, 3, 4, 5]
Care & Cultivation
- Sunlight: Prefers full sun (at least 6 hours of direct light) for the most vibrant and abundant flowering, but tolerates light shade. [1, 2]
- Soil & Water: Thrives in rich, well-draining soil with a pH between 6.0 and 7.0. Water about an inch per week, and provide extra moisture during hot, dry spells or when the plant is actively blooming. [1, 2]
- Fertilizing: Apply a balanced fertilizer (like 10-10-10) in the spring, and use a low-nitrogen formula by mid-summer. [1]
- Pruning & Maintenance: Remove spent blooms (“deadheading”) to keep the plant looking tidy and encourage new buds. Trim back dry or yellowed foliage after the blooming season finishes. [1, 2]
