Bulbs are easy to grow and add color and texture to the garden. While some, like caladium and Elephant Ears, are grown for their foliage. Others, like tulips, cannas and daffodils, make excellent cut flowers for bouquets and fresh floral arrangements. Some flower bulbs are planted in the spring, while other bulbs are planted in the fall. Some bulbs are winter hardy, meaning they can stay in the ground over winter, while others are tender bulbs, meaning they must be dug up or lifted in the fall in cooler grow zones. All bulbs grow best in well-drained soil. When selecting bulbs to buy online, consider whether they grow best in full sun or in shaded conditions, plant height, bloom time and their hardiness zones.
