ALLIUM hollandicum
Dutch Ornamental Onion
Dutch ornamental onion sprouts a softball-sized globe of purplish pink, star-shaped flowers in the summer. The flower stalk rises several feet as the large, strappy leaves die back. This species is a natural hybrid variant of Allium aflatunense, which is native to central Asia. Alliums are in the onion family and thus release the familiar pungent fragrance when their leaves or stems are crushed. It thrives in well-drained, even sandy, neutral soil in full sun.
Plant this bulb in the autumn four inches deep (10 cm)in well-drained neutral soil. Onions are drought tolerant once they are established. Decrease the watering when the foliage starts to fade. Alliums have a tendency to self-sow; lift and divide the clumps only when they become crowded. Grow this ornamental onion as an exclamation point in the garden. Since the tall flower stalk is bare, plant it among large-leafed, mat-forming perennials, such as black-eyed Susan. Or, try it in the vegetable patch amid the foliage of squash or pumpkin. Be sure to plant extra since this onion is a long-lasting cutflower; it also dries well.
