Perhaps the tallest of the ornamental onions, Allium giganteum is a striking and bold addition to the garden with its star-shaped, tiny lilac-purple flowers forming a 5-6 in. wide (12-15 cm) globe-shaped cluster. Blooming in late spring to early summer, this Giant Allium enjoys long-lasting blooms and remains ornamental in the garden well into summer. A perfect background plant. Great in fresh or dried flower arrangements too!

A favorite of many gardeners, multiple award-winner Allium 'Purple Sensation' is a striking ornamental onion with its inflorescence consisting of dozens of small, star-shaped, rich violet-lilac flowers, forming perfectly round flowerheads, 3 in. wide (8 cm). They are borne atop sturdy stalks, which arise from a group of 6 to 8 handsome, blue-green, straplike leaves. Blooming in late spring to early summer, this spectacular Allium enjoys long-lasting blooms and makes outstanding cut flowers. It will last as a cut flower for 2 weeks!
