This plant is known by several common names: Ismene, Spider Lily, Basket Flower, Sea Daffodil and Peruvian Daffodil. Its botanical name is Hymenocallis Sulphur Queen. Peruvian Daffodils are relatives to the Amaryllis family and produce strap-shaped, amaryllis-like leaves that grow directly from the bulb. Its fragrant, exotic blooms resemble a white, spidery daffodil with the daffodil-like center cup or corona.

Growing Instructions
Plant Hymenocallis in the spring after all danger of frost has passed. Hymenocallis performs best in full sun but will grow in partial afternoon shade. The ideal soil is rich and porous and drains well, yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed and incorporate into the soil to a depth of 10 inches. Plant bulbs 3-4" and 6-8" apart. Cover with soil. When planting a large number of Hymenocallis in one bed, excavate the entire area to the recommended depth, work fertilizer into the bottom of the trench, set out bulbs and then cover all at once. Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach roots. Mulch to keep the soil cool and to prevent the soil from drying out. Fertilize monthly. Discontinue watering when leaves begin to turn and fade back. Lift and store over winter if planted in colder climates. Mulch in milder climates to protect from frost.
Care Tip
Hymenocallis produce lots of thick roots and will need a container that is sized for them to grow.Plant in containers with the necks of the bulbs peeking slightly above the soil surface. Hymenocallis prefer moist soil in the spring but need dryer soil summer through winter.
