Narcissus 'Sundial'
Jonquilla, Sundial Daffodil
The rounded, fragrant, bright citron-yellow flowers of this Jonquilla hybrid are ornamented with small, shallow, slightly darker yellow cups. The petals are slightly backswept and the cups are ribbed and wavy-edged. The flowers cluster atop compact, shin-high stems in early spring. This cultivar was introduced in 1955 by famed daffodil hybridizer Alec Gray.
Daffodils are hardy, long-lived, clump-forming bulbs. Unlike tulips they are poisonous, so they are not eaten by small mammals and their green tops are not browsed by deer.
These are some of the easiest bulbs to grow. They prefer full to part sun and require average to fertile soil. After blooming, it is good to let their green tops photosynthesize to allow them to store plenty of fuel for next spring’s display. Once their leaves start to turn yellow, they can be cut to the ground. Jonquilla hybrids are somewhat less cold-hardy and more heat-tolerant than most other hybrid narcissus, and make excellent choices for areas such as the Southeast United States. Dig and divide bulbs in summer if bloom and vigor wane.
Like all daffodils, 'Sundial' is a superb cutflower. It also is ideal for forcing. In the landscape, it pairs well with tulips, muscari, hyacinths, and spring-blooming perennials and shrubs.
