Allium flowers or ornamental onions are a genus (Allium) of several hundred attractive flowering plants with spherical blooms. They belong to the family Amaryllidaceae. Allium flowers are bulbous, herbaceous perennial plants with specific garlic or onion odor from basal foliage. Allium flowers are sometimes referred to as flowering onions or onion flowers.

The flowers are small (~2.5 cm), six-petalled, and grouped in a cluster at the top of the leafless stem. Allium flowers come in various colors, shapes, and sizes. The flower color can be white, red/burgundy, purple/violet, pink, white or yellow. The flower stem is elegant, slim, and erect, and the bloom is showy and long-lasting. 

Depending on the species, the flower can have a star, bell, cup, or tubular shape, and the stem can be from 15 cm to 1.5 m tall. Some varieties have domed or flat-topped blooms.

Etymologically, the genus name Allium is of Latin origin and means garlic which, along with onion, leek, chives, scallion, and shallot, is a type of allium plant. According to some sources, the root of the word Allium is the Greek word “aleo,” meaning “to avoid”—a reference to the strong odor of the plant. 

Due to this strong odor, Christian myth associates the allium flower with the Devil. According to this myth, the flower blossomed where the Devil left his footprints in the soil on the way out from the Garden of Eden. His left foot produced garlic allium flowers, and his right foot produced onion allium flowers.

Many allium flower species are native to the northern hemisphere—North America and Eurasia. Some allium species grow on high mountain peaks, such as Mount Everest. Only a small number of allium species are found in South America (Chile and Brazil) and parts of Africa.

Some allium plants (including onion) are among the oldest cultivated plants in the world, with evidence that they have been grown in India, China, and the Middle East. In the late 19th century, Russian botanists collected allium species from Central Asia and began cultivating them in the Botanical Garden in St. Petersburg. The British horticulturalists, intrigued by the beauty of these flowering plants, went on to new expeditions and discovered other allium flower varieties.

In their natural habitat, they prefer dry forests and mountain regions. As cultivated plants, they have a wide geographical distribution, and they sometimes behave like weeds. Most allium flowers bloom between late spring and early summer.

What does the Allium flower symbolize?

The symbolism of unity comes from the fact that the flowers are clustered into a single spherical bloom and develop from a single bulb. Onion is one of the better-known members of the genus of allium flowers. The word “onion” comes from the Latin word “onio,” meaning “unity” or “one.”

Ancient Egyptian inscriptions and drawings indicate that allium plants were prominently used in their culture. The Ancient Egyptians were fascinated by the spherical shape of the allium flower and saw it as a symbol of the universe. In their rituals, they also appreciated the layers and the concentric rings of a sliced onion plant (Allium cepa), in which they see a symbol of eternal life.

In the symbolic flower language of the Victorian Era, the allium flower meaning was “you are strong,” “you are elegant,” and “you are perfect.”

Allium flowers (especially the common onion or Allium cepa) have often been ascribed the power to bring money, wealth, and prosperity. It is believed that dreaming of Allium sativum (common garlic) announces good fortune. The Bolognese used to buy allium bulbs at the festival of St. John, believing that this would protect them from falling into poverty. Another allium flower meaning is patience—it is derived from the fact that these flowers bloom slowly.

In Sanskrit, the sacred language of Ancient India, the word for garlic allium means “slayer of monsters.” In many countries, allium is believed to ward off bad luck, evil forces (including witches, ware-wolves, vampires, and the Devil), sickness, and disease. 

In Germany, allium is known as ‘the ordinary man’s armor.’ The 16th-century botanist Clusius wrote that the German miners used allium as a powerful ally. They believed that it defended them from the assaults of impure spirits which often roamed in and around mines.

All in all, the allium flowers symbolic meanings are:

  • good fortune
  • prosperity
  • unity
  • patience
  • humility
  • grace

How to grow Allium flowers

Although hybrid alliums can be grown from seed, you may have to wait a year or longer for them to bloom.

  1. The allium bulbs should be planted in the fall, just before the ground freezes. With the spiked end up, plant them twice as deep as the bulb’s height.
  2. Generally adaptable to soil types; however, it’s crucial to remember that they require well-drained soil.
  3. Avoid moist areas since they can cause rotting, especially when they are dormant.

How to care for Allium flowers

  1. Trim the flower scapes when they wilt, keeping the stem as short as possible.
  2. Only remove leaves that have begun to turn yellow, as the bulb is accumulating nutrients for the forthcoming flowering cycle at that stage.
  3. There is no need for fertilizer.
  4. Remember to frequently water allium plants in pots because they require more water and dry up faster.
