Best planted in late fall. In some areas, gardeners treat flower bulbs as annuals. For an informal look, plant in groups in natural swathes or bouquets. In USDA zones 8-10, refrigerate the bulbs for no less then eight weeks. In the garden, plant them before frost, but not as early as in the northern part of the country. Planting them in a lightly shaded area will keep them cool and prolong blooming.
