Cheerful daffodils are classic spring flowers. For a natural look, toss them around your yard or landscape and plant them where they fall. Choose big, healthy bulbs and plant them 6" deep about 2 to 4 weeks before your ground freezes. They need sun to part sun and will come back year after year; they're hardy in USDA zones 3-8. 'Sunshine Boys,' pictured here, is a blend of early-blooming daffodils.
When tulips, daffodils and lilies burst into bloom, you’re probably not thinking much about the part of the plant that’s underground: the bulb. Flower bulbs are actually a type of food storage organ, a way that plants stash their homemade nosh to help fuel future growth and flowers. Many plants get lumped under the heading bulbs, including tubers, corms and rhizomes. Knowing a little about different types of bulbs can help you understand how these plants grow—and how you should handle them at planting time.
