The ‘Two Part Harmony’ daylily (Hemerocallis) is a highly sought-after, early-season double daylily renowned for its unique, multi-layered petals. Hybridized in 1996, it features eye-catching straw-yellow blooms with a striking wine-red eyezone, a matching saw-tooth edge (picotee), and a contrasting green throat. [1, 2, 3, 4, 5]
Key Characteristics
- Bloom Size & Height: Produces 4-inch flowers on tall, strong scapes measuring roughly 34 inches (86 cm) tall.
- Bloom Season: Flowers early in the daylily season (late spring to early summer) and is known for reblooming.
- Foliage Type: Evergreen, meaning it retains its foliage year-round and adapts well to various climates.
- Ploidy: Tetraploid. [1, 2, 3]
The “Double” Trait
What makes ‘Two Part Harmony’ fascinating is its unpredictable doubling. In warmer climates, it will double nearly 100% of the time, while in colder zones, it doubles about 50-80% of the time. Interestingly, individual plants often alternate—producing single blooms early in the season and transitioning into full, fluffy double flowers as the season progresses and the plant matures.

Growing Tips
- Sun & Soil: Thrives in full sun to partial shade and prefers moist, well-drained soil.
- Maintenance: Deadhead spent blooms after they fade and fertilize in early spring to encourage maximum bud count (typically 20–25 buds per stalk).
- Hardiness: Highly adaptable and easy to grow across a wide range of zones. [1, 2, 3, 4]
