Ornamental Allium bulbs are a part of the diverse genus with include both flowering types for the garden and the well known edible species, both types are available for sale online.
Although they sometime refered to as 'ornamental onions' it is more correct to call them 'ornamental alliums', all leeks, garlic and onions are alliums. But all Alliums are not onions.
The ornamental alliums smell a little like their cousins, however they are grown for the flowers, many are very colorful, and some of the flowers are large and imposing. The best varieties have stunning flowers, usually on very upright stems.
They fit well into the perennial border and have made many an appearance at flower shows, including the Chelsea Flower Show.
Grown in the garden border mainly for the long lasting flowers which appear in late spring to summer depending on zone and variety these wonderful bulbs vary greatly in both colour and plant size.
As these plants give off the traditional 'garlic' or 'onion' sulpher smell they also tend to deter rhodents, even deer tend to shy away from then, however I would not call them 'deer proof'.
