Flowering Onion (Allium cepa 'Gladiator') - Description
Its size and appearance make it a show-stopper in the late June garden and in large bouquets. Each huge flower head (up to 6" in diameter) is a globe like cluster of hundreds of tiny, lilac purple flowers. Strong, tubular stems, they are dramatic at the back of the border. Astonishing in size and color, they fill the gaps in the late spring border. Alliums are a great transitional flower, providing drama in the late spring and early summer garden. Alliums give weeks of bloom. Fresh cut or dried, they are a flower arranger's delight. They are easy to grow and multiply and increase in beauty each year, providing more and more stems and blooms for years to come. And you will be glad to know that critters that dig up and eat other bulbs in your garden won't go near them!

Flowering Onion (Allium cepa 'Gladiator') - Interesting facts
Allium is a diverse genus of bulbous perennials that includes such plants as onions, garlic, chives, leeks, society garlic and giant ornamental onions. They all have relatively high concentrations of sulfur compounds which give them their unique smells and flavors. When the plant tissue is damaged some of these sulfur compounds are released, which explains why we cry when we cut onions. The sulfur compounds can dissolve in our tears, where it forms sulfuric acid. In response to the acid in our tears, we blink and produce more tears. This gives the impression that cutting onions makes us cry.
