Allium x 'Gladiator'

Ornamental Onion

An all time, award-winning favorite of horticulturists the world over! Allium ‘Gladiator’ is notably one of the tallest Ornamental Onion selections available on the market. With its globe-shaped inflorescences reaching 3-4’ in height, this late spring blooming perennial is sure to make quite a statement in the cottage garden or as a vertical element in a container planting, with its outstanding garden performance landing it the coveted Award of Garden Merit by the RHS. Long-lasting blooms begin to appear towards the end of May and persist into early July overtop of arching, strappy foliage that can create a windswept appearance if planted en masse. Each rose-purple, pom-pom like inflorescence has individual star-shaped florets dotted with green centers, which are often visited by a variety of bees, butterflies, moths, and other pollinating insects. The fragrant foliage of ‘Gladiator’ Ornamental Onion makes for a lovely addition to the sensory garden, and is luckily unpalatable enough that hungry deer will leave it alone.
