Allium is a genus of more than 800 species of bulbous perennials in the family Amaryllidaceae, native to the Northern Hemisphere, but cultivated all over the world.
These plants come in a broad palette of colors, shapes and sizes. They are edible, but also very useful in multiple ornamental settings. Ornamental Alliums, also known as Ornamental Onions, have globe-shaped clusters of flowers in shades of purple, pink, blue, white and yellow. They have some of the most attractive blooms in the plant kingdom!
The word “allium” comes from the Latin word for garlic. However, this name was taken over by Carl Linnaeus for the entire genus.
Ornamental Alliums are commonly known as “Ornamental Onions” because of their beautiful stature.
Allium represents strength, patience, good fortune and prosperity.
Interesting facts about Allium
Benefits and Uses
Members of this genus are edible andcultivated worldwide. However, species that are bred specifically as ornamentals may be less palatable. Alliums include some of the most ancient cultivated crops such as garlic, onion, chive and leek. All parts of the plant 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.
