Allium 'Globemaster' 23W20 ornamental onion E4-
Allium 'Globemaster' 23W20 ornamental onion E4- (Jan Bijl, 1971) ornamental onion, Mature plant size: 3ft., Purple, USDA Hardiness Zone 5-7, Michigan Bloom Week ISO WW20, In Garden Bed E4 for 6.6 YEARS (MBulb). Planted in 2016.
Missouri Botanical Garden: 'Globemaster' is a hybrid cross between A. christophii and A. macleanii. It is a bulbous perennial that is ornamentally grown for its spring bloom of spherical, deep lavender flower heads. Strap-shaped, gray-green, basal leaves form a clump of foliage in spring. As the leaves begin to wither in mid-spring, stout flowering stems rise to 20-30" tall topped with huge, globular, deep lavender to silver-purple flower heads (terminal umbels to 6-10" in diameter) packed with individual star-shaped florets which collectively display a metallic sheen. Flowers appear in an impressive, long-lasting, spring bloom (May in St. Louis) in which new florets continue to develop as the original ones fade. Flower heads dry after bloom and remain ornamental in the garden well into summer. Flowers generally lack fragrance. I only see 2 of the 3 in 2020. Looking sad in 2021.
