Flowering Onion
Enormous globes of flowers on tall, slender stems. Beautiful when planted among early-flowering perennials, bulbs and shrubs where the onion flowers seem to hover over the other plants. Excellent cut flower, lovely in bouquets. Plants disappear shortly after blooming, but return each spring for another display.
