This flowers from this easy-care bulb may be short, but they're big on bold color, especially when planted in large groupings in a rock or woodland garden. Like other bulbs, Iris reticulata 'Harmony' requires full sun (at least six hours a day) and well-drained soil. Plant the spring-blooming bulbs in autumn, placing them 4 inches deep in the soil.
