Peruvian daffodils (Hymenocallis narcissiflroa) look somewhat like daffodils, with spidery petals surrounding the central flower cup. These tender perennials grow in U.S. Department of Agriculture plant hardiness zones 9 through 11, but they can thrive in any climate with proper winter care. The bulbs tolerate annual digging and they spend winter dormant, which allows you store them indoors. Store the bulbs in fall before the first hard frost begins to freeze the soil, but after the foliage has died back naturally.
1 Loosen the soil around the clump of bulbs with a trowel. Dig below the bottom of the bulbs then slide the trowel under them and lift the bulbs out of the soil. Handle the bulbs gently so the fleshy roots don't break.
2 Rinse the excess soil off each bulb with a brief spray of water. Spread the bulbs out in a shaded area and allow the bulbs to dry.
3 Fill a shallow box with a 3-inch layer of dry vermiculite. Lay the bulbs upside down on top the vermiculite then add more vermiculite to cover the bulbs.
4 Store the Peruvian daffodils in an area that stays between 60 and 65 degrees Fahrenheit until spring. Choose a place that's dry so moisture doesn't cause the bulbs to rot during storage.
5 Plant the stored bulbs into the garden in spring after frost danger has passed. Plant the bulbs in a well-draining, partially shaded bed, setting them 2 inches deep and spacing them 8 to 12 inches apart.
Items you will need
- You can leave Peruvian daffodils in the soil in mild climates that rarely experience winter freezing or wet winter soil. Mulch over the bulbs in fall to provide additional cold protection.
- Peruvian daffodil bulbs are mildly toxic if eaten, so keep them away from children and pets.
