Allium Chives

Usually bulbs are thought of as something separate from perennials because they seldom persist throughout the garden season. Chinese chives, or garlic chives, can be lifted and divided like any other perennial and, even when not in bloom, the foliage is attractive. In addition, they provide blossoms in late summer when most other plants are through.
