Family
Liliaceae
Botanical Name
Allium 'Globemaster'
Plant Common Name
Globemaster Ornamental Onion, Ornamental Onion
General Description
For many, ‘Globemaster’ is the standard against which all other ornamental alliums are judged. The gigantic, rounded, lavender-purple flowerheads of this hybrid are composed of small, starry, densely packed florets, and can approach the size of a volleyball. Appearing in late spring, they are borne singly on tall, sturdy stems which rise above bold, strappy, deep green basal leaves that appear in spring and fade as the plants bloom.
In autumn, plant the bulbs of ‘Globemaster’ in fertile, well-drained soil at a depth of two to three times their diameter. Full sun is essential for best flowering, and drier summer soil conditions are beneficial. Plant singly or in small groups among the foliage of other plants in order to mask the dying foliage at the base of the stems. From year to year, the flowerheads of this perennial will increase in number, but become somewhat smaller in size. Lift and divide the bulbs only if they become crowded.
Give this dramatic perennial a starring role in the mixed border or rock garden, or use it to dress up the vegetable garden. Bulbous alliums such as this are wonderful combined with other late spring to early summer bloomers such as Siberian iris, roses, and meadow sage. They also make excellent, long-lasting cut flowers, and add punch to both fresh and dried flower arrangements.
