Allium ‘Globemaster’ (Ornamental Onion)

Boasting the biggest flower heads, multiple award-winner Allium ‘Globemaster’ is a striking ornamental onion with huge inflorescences packed with dozens of small star-shaped violet flowers forming a 10-inch wide (25 cm) globe-shaped cluster! Blooming in late spring to early summer, this spectacular bulbous perennial enjoys long-lasting blooms, and its seed heads are ornamental, persisting for weeks after the flower has passed.

• Recipient of the prestigious Award of Garden Merit by the Royal Horticultural Society.
• Growing up to 28 – 36 inches tall (70 – 90 cm), this beauty naturalizes easily and will come back year after year!
• Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained soils in full sun. This Allium is drought tolerant.
• Known for attracting bees, butterflies, ​moths, and other pollinators, but deer ignore it.
• Stunning in beds, borders, and cottage gardens. Spectacular in large sweeping drifts. Plant in groups (at least 10 to 15 bulbs) for the best visual impact. Excellent as cut flowers for both fresh and dried arrangements!
• 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.

Hundreds of Allium species exist, but only a few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their remarkable 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. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing. All species can be used in the border.
