The Whistler daylily (Hemerocallis ‘Whistler’) is a classic, midseason-blooming daylily introduced in 1971. It produces large 6-inch blooms on 32-inch scapes and is highly regarded for its beautiful, solid yellow flowers with a bright green throat. [1]
Key Features

- Color: Yellow self with a green throat.
- Plant Size: Grows to about 32 inches tall, with flowers spanning roughly 6 inches across.

Care & Cultivation
Like other resilient daylilies, ‘Whistler’ thrives in USDA hardiness zones 3-9. It is incredibly easy to grow and prefers full sun to partial shade. Daylilies are adaptable to most soil types, whether sandy or clay, and are known to be drought-tolerant once established. They require minimal maintenance and can be divided every few years if they become overcrowded. [1, 2, 3, 4, 5]
