Planting Asiatic and Oriental lily bulbs is an easy way to add cheer to the summer garden—and to have a supply of cut flowers for bouquets and arrangements. Asiatic lilies bloom in early to midsummer while Oriental lilies bloom in mid to late summer. Grown from bulbs, lilies are sun-loving perennials that grow best in well-drained soil. When buying lily bulbs for sale online, you can choose from a wide selection of flower colors, including red, pink, orange, white and other hues. Some lily flowers are also very fragrant. Most lilies can be grown in zones 3-8. Other factors to consider when selecting lilies are their mature height and spread, bloom time and flower color.
