ALLIUM hollandicum 'Purple Sensation'

Ednie Flower Bulb, Inc.

Family

Liliaceae

Botanical Name

ALLIUM hollandicum 'Purple Sensation'

Plant Common Name

Dutch Ornamental Onion

General Description

Closely allied to Central Asian species such as Allium stipitatum, this ornamental onion of garden origin bears softball-sized globes of violet-purple flowers on tall stems in late spring. The strappy basal leaves wither at flowering time. The bulbs and crushed leaves give off the familiar "onion smell".

This perennial thrives in fertile, well-drained soil in full sun. Plant it in fall and keep it well watered through the growing season. Lift and divide the bulbs only if they become crowded. Grow 'Purple Sensation' as an exclamation point in the garden. To hide the withering leaves, 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 works well as either a fresh or dried cut flower.
