A favorite flower for the summer garden and cut-flower displays, lily bulbs are easy to grow in the sunny garden—and some lily varieties are suitable for patio containers, too. Many lily flowers are fragrant and attract pollinators. When choosing lily bulbs to buy online, consider their height, bloom time, hardiness zone and color. While some lilies can grow up to 4 ft. tall, border lilies are shorter and ideal for containers and the fronts of borders. Lily bulbs can be planted in the spring and fall. Lilies look best when they are planted in groups. For best results, plant lily bulbs in well-drained soil in full sun to partial shade.
