Allium 'Gladiator' has large, fragrant lavender-purple spheres the size of soft balls on 3-4 foot stems. Few plants can offer the unique flower forms of ornamental onions. Every garden should have Alliums. Plant in multiples of 3, 5, 7 or more. Don't fret when foliage starts to die back just before flowering. It's normal. Just trim the leaves.
