The “Buttercup” daylily (Hemerocallis) is a highly popular, low-maintenance perennial prized for its vibrant, golden-yellow trumpet-shaped blooms. While individual flowers last for only a single day, the plant produces a continuous succession of buds, ensuring prolific blooming throughout the summer. [1, 2, 3, 4, 5]
📌 Key Characteristics
- Appearance: Features clear, buttercup-yellow single or double blooms that can measure 3 to 6 inches across. Many cultivars have ruffled edges or a contrasting bright green/lime throat. [1, 2, 3, 4]
- Plant Size: Typically reaches a height of 24 to 36 inches, making them ideal for borders, mass plantings, and mixed gardens. [1, 2]
- Habit: Diurnal (blooms open during the day) and are often lightly fragrant. [1, 2]
- Edibility: Unlike true lilies, daylily blooms (including the ‘Buttercup’ variety) are fully edible and make a colorful, sweet, or savory addition to salads and other culinary dishes. [1, 2, 3, 4]
☀️ Growing and Care
- Sunlight: Thrives in full sun to partial shade. (Requires at least 6 hours of sunlight daily for maximum bloom). [1, 2, 3, 4]
- Soil: Highly adaptable, but prefers fertile, moist, and well-drained loamy soil. Once established, they display excellent drought tolerance. [1, 2, 3]
- Hardiness: These cold-hardy perennials are suitable for robust growth in USDA Hardiness Zones 3 through 9. [1]
- Maintenance: Very low maintenance. You can simply pluck off (“deadhead”) spent blooms to encourage more flowering and prune back foliage in late fall. [1, 2]
