Lilies are some of the most recognizable and beloved flowers in the summer garden. Their elegant flowers add cheer to the garden and are stunning in bouquets and fresh floral arrangements. Gardeners can choose between Asiatic and Oriental lilies. Asiatic lilies bloom in early to midsummer while Oriental lilies bloom in mid to late summer. Planting both types ensures months of beautiful blooms. These sun-loving perennials are grown from bulbs and perform best when planted in well-drained soil. Lilies are available in an array 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.
