Benefits and Uses

All members of this genus are edible and cultivated worldwide. However, species that are bred specifically as ornamentals may be less palatable.
The Alliums include some of the most ancient cultivated crops, such as garlic, onion, chive and leek. All parts of the plants are edible, although only the bulbs and leaves are usually consumed.
All species contain organic compounds called organosulfoxides, particularly alk(en)ylcysteine sulfoxides. which give them a distinctive odor and taste. Organosulfoxides are safe to humans, but can cause toxic reactions in your pets so keep these plants away from them!

Alliums are great garden plants because of their elegant slender stems and globular blooms. They don’t take up a lot of space and will bring color and height to any garden.
Known for their perfectly round shape and beautiful colors, Alliums are also great for any flower arrangement.
