Lilies are an easy-to-grow, versatile choice for mixed perennial flowerbeds or mass plantings. Their colorful, bell-shaped, often fragrant flowers open during the summer months. Not only do lilies add pops of color and cheer to the summer garden, they look outstanding in fresh floral arrangements and bouquets. For a spectacular display, choose a variety of lilies, including ones with single and double blooms, as well as lily trees and shorter border lilies. While lilies aren't super fussy about soil, they prefer sunny locations and will grow in full sun or partially shaded areas that receive several hours of direct sunlight.
