Ornamental Features

Globemaster Ornamental Onion features bold balls of lightly-scented rose flowers at the ends of the stems from late spring to early summer. The flowers are excellent for cutting. Its sword-like leaves remain green in colour throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Globemaster Ornamental Onion is an open herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This is a relatively low maintenance plant, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting butterflies to your yard but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Globemaster Ornamental Onion is recommended for the following landscape applications;

  • Vertical Accent
  • General Garden Use

Planting & Growing

Globemaster Ornamental Onion will grow to be about 12 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 12 inches. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This particular variety is an interspecific hybrid. It can be propagated by multiplication of the underground bulbs; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

 

Description by Florissa 

A magical garden globe that truly brings life into the garden. Allium ‘Globemaster’ is brimming with densely packed, small, deep lavender florets that collectively gather to form a 25 cm (10”) sphere. One of the largest flowering alliums, it is a cross hybrid between alliums christophii and macleanii, and many think it is one of the best, especially the adoring bees and butterflies. Having received the coveted RHS Award of Garden Merit, ‘Globemaster’ adds an unusual structural effect to the garden: the giant spheres look like silvery purple floating bubbles blown from a wand. Alliums are ornamental onions, and their foliage when crushed has an onion-like fragrance, but the flower-heads are unscented and make excellent cut flowers. Terrific in the border among giant beauty tulips, ‘Globemaster’ is also a good companion among roses, helping ward off unwanted pests and disease. Deer and rabbit resistant, this allium grows to 95 cm (38″) and returns reliably year after year and requires little maintenance after planting. Just allow the foliage to die back completely. Easily grown in full sun to partial shade locations and well-draining soils. Plant the bulbs 10 cm (4”) deep, spacing them 30 cm (12”) apart. Hardy to Zone 5.
