Award winning Allium Gladiator is one of the tallest of the ornamental onions. With sturdy stems reaching as high as 100 cm (40 in) and huge globe-shaped flowers up to 15 cm (6 in) across, each showy sphere consists of dozens of small, star-shaped lavender-blue flower clusters with a sweet fragrance. These charming perennials give gardens amazing architectural structure, especially when planted in groups of three or more towards the back of mixed borders. Known for attracting butterflies, bees and other pollinators, Allium Gladiator naturalizes easily and will come back year after year.
