Plant bulbs in fall, point up, 4 in (10 cm) deep and about 4 in (10 cm) apart. Choose full sun or light partial shade, then water deeply after planting. In spring, keep the soil slightly moist if rainfall is insufficient, but avoid standing water. A thin layer of mature compost supports growth; avoid nitrogen-rich fertilizers. Group the four bulbs for a more visible effect. When growing in containers, use a deep pot with drainage holes and protect it from repeated freeze-thaw cycles. After flowering, remove spent flower stalks if you don’t want seed formation, but let all the leaves yellow completely. They replenish the reserves needed for the next bloom. Reduce watering during summer dormancy and mark the location to avoid disturbing the bulbs. Divide a crowded clump after the foliage has dried, then quickly replant firm bulbils. Ornamental bulbs are not for consumption and may irritate the skin; keep them out of reach of children and animals and wear gloves if necessary.
