Allium stipitatum ‘White Giant’ (Ornamental Onion)

One of the tallest white Alliums, Allium ‘White Giant’ features huge globes, 6-8 in. wide (15-20 cm), densely packed with hundreds of snow-white flowers adorned with emerald green eyes. They are borne atop sturdy, upright stems and rise above the foliage of upright, strap-shaped, glossy green leaves. Blooming in late spring to early summer, this very architectural bulbous herbaceous perennial is perfect for growing in a mixed herbaceous border and makes an excellent cut flower. Leave the seedheads over winter to provide winter interest.

• Growing up to 3-4 ft. tall (90-120 cm), this beauty naturalizes easily and will come back year after year!
• Easily grown in fertile, well-drained soils in full sun. This Allium is drought tolerant.
• Stunning in beds and borders, city gardens, cottage gardens, gravel gardens, or containers. Spectacular in large sweeping drifts. For best visual impact, plant in groups (at least 10 to 15 bulbs). Excellent as cut flowers for both fresh and dried arrangements.
• Known for attracting butterflies, and other pollinators, but deer ignore it.
• Mixes beautifully with other late spring flowering bulbs and creates stunning combinations with pink or white delphiniums, peonies or irises.
• To be planted in fall.
• No serious pest or disease issues. Keep an eye out for slugs, snails, leaf miner, onion fly, onion white rot, and downy mildew.
• Propagate by division, removing offsets, in autumn.
• Allium stipitatum is native to central and southwestern Asia.

Many hundreds of Allium species exist, but only a modest few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their great diversity in color, inflorescence and flowering height. Many species bloom in early summer – just after the spring-flowering period and just before the exuberant full bloom of summer. All species can be used in the border. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing.
