Round-Headed Leek (Allium sphaerocephalon 'Purple Drumstick') - Description
Use in the mixed border or rock garden with yellow daylilies. 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. Planted in groups, they add drama, height and an airy lightness to a mixed perennial border of iris, peonies, bleeding hearts, Asiatic lilies, daylilies and Hosta. The shorter Alliums are ideal clustered in rock gardens or at the front of a border. All Alliums give weeks of bloom. Fresh cut or dried, they are a flower arranger's delight. They are easy to grow as long as they have very well drained soil and plenty of sun. They 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!

Round-Headed Leek (Allium sphaerocephalon 'Purple Drumstick') - 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.
