Hymenocallis ‘Sulfur Queen’ Peruvian Daffodil is an early to mid-summer sun-loving bloomer. It has a marvelous citrus fragrance with flowers in clusters of 2 to 3 (or more), each flower up to 6-inches across on an 18- to 24-inch stem. Its frilled primrose yellow cup is similar to a daffodil with a green-stripped throat and large golden stamens. Six narrow petals surround the cup. It is deer-resistant and a lovely cut flower lasting over a week in the vase.
