PURPLE power
It’s hard to imagine life without onions, either wafting delicious garlicky odours around the kitchen or as zesty ornamental flowers that spice up any garden with their luscious blooms in pinks, purples, yellows, blues or whites. Peeling back the many layers of the ornamental onion family reveals such an amazing array of different flower forms, colours and sizes, and unbelievably, they are all closely related.
Ornamental onions range from midgets to supersized Allium ‘Gladiator’; from the small snowy globes of ‘Ivory Queen’ to the lofty heights of ‘Mont Blanc’ or ‘Mount Everest’; blue or golden , blush or, last but by no means least, the ubiquitous ‘Purple Sensation’ — a legend that more than lives up to its billing.
