Allium 'Ambassador' has fantastic six inch spheres on tall stems that bloom between 'Globemaster' (May) and A. giganteum (June/July). Indispensable for keeping the ornamental onions going all season long! 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.
