Plant your hyacinth bulbs close together for a dramatic display, either in groups of one color or as a rainbow of several shades. Many gardeners think they look best in close groups of 3, 5 or more. Hyacinths must have good drainage, so be sure to plant them where they'll never be in standing water. With some shade, the flowers will last longer than in full sun. And next spring, don't forget to stop and smell the hyacinths!
