About the Allium Flower

The Allium Flower — Family, Genus, and Taxonomy
Allium is a genus of flowering plants that belongs to the Allieae tribe of the subfamily Alliodeae under the Amaryllidaceae family.
There’s a dispute over exactly which plants belong to the genus because it has a complicated taxonomy of evolutionary lines. As a result, species estimates range from about 260 to just under a thousand.
Botanical Characteristics, Colors, and Fragrances
Allium flowers are herbaceous plants that grow from bulbs and have a distinct onion or garlic odor or flavor. They produce green leaves that vary from straight or coiled to broad.
They produce several blossoms with globe-shaped or cascading blooms in shades of purple, blue, pink, red, yellow, and white. Blooms feature clusters of small flowers.
Popular Allium Flower Types, Species, and Cultivars

Etymological Meaning

To What Regions Are Allium Flowers Native?
Apart from a handful of species found in South America, all species from the Allium genus are native to the northern continents.
When Are Allium Flowers in Season?
Depending on the species and your growing zone, allium flowers bloom from late spring through early summer.
Uses and Benefits of Allium Flowers

Culinary Uses and Economic Importance
Alliums used in recipes around the world include onions (Allium sepa), garlic (Allium sativum), chives (Allium schoenoprasum), leeks (Allium ampeloprasum), shallots (Allium oschaninii), and scallions (several species).
These species are popular in every culture’s cooking, and they drive a large part of the agricultural crop economy.
Ornamental Allium
We love culinary alliums for their strong flavor and aroma, but other alliums don’t have the same strong scent. We cultivate ornamental alliums simply for the inherent beauty of their blossoms – not for harvest.
Allium in Herbalism
In herbalism, Allium sativum, which you know as garlic, has some of the strongest, natural antimicrobial properties of any plant. Eaten whole or taken as an oil, garlic has been used to help ward off bacterial, fungal, and viral infections. It’s also been used as an antispasmodic, hypoglycemic, expectorant, antihistamine, and more.
Alliums & Vampires
Legend has it that garlic is also one of the best ways to ward off vampires. Perhaps famously pungent garlic breath is scary enough to do the trick?
Perfect for Pollinators

Most pests don’t like the distinct garlicky/onion aroma of allium plants, which keeps them safe from pesky deer and rabbits. Yet, their blossoming clusters of flowers are attractive to pollinators and will bring plenty of bees and butterflies into your garden.
Toxicity to Pets
While alliums provide popular cooking ingredients for humans, they’re toxic to dogs and cats. So, be careful with your pets around all allium plants including the ones we eat.
Allium Flower Meaning and Symbolism by Color
In the language of flowers, Alliums carry the symbolic meaning of good fortune, patience as well as grace. Since many blossoms sprout from a single bulb, they also represent unity.
In the Victorian Language of Flowers, the color of flowers holds a significant meaning. Different varieties of alliums bloom in shades of purple, blue, burgundy, white, pink, orange, and yellow. Including these colors in a bouquet conveys the following symbolic meanings:
Purple Allium Flower Meaning

This hue is classically royal and can represent royalty and respect. They also carry a strong air of admiration and tradition.

The Meaning, Symbolism, and Cultural Significance of Allium Flowers
Apart from their colors, allium flowers of any color have a variety of general symbolic meanings. Since many blossoms sprout from a single bulb, they represent unity. Slow to bloom, they symbolize patience. Additionally, they represent humility, prosperity, and good fortune.
People have cultivated allium plants (especially culinary varieties) for millennia. As a result, they’ve become culturally significant around the world for their use in cooking, medicine, and worship. They appear in the Bible and the Quran. William Shakespeare even references their ability to move one to tears in The Taming of the Shrew.
How to Grow and Care for Allium Flowers at Home

What Growing Zones Are Suitable for Allium Flowers?
Allium bulbs are winter-hardy in growing zones 3 through 8. Their performance in each zone varies depending on the species you grow.
Where Should I Plant Allium Flowers?
Plant allium bulbs in perennial gardens, rock gardens, kitchen gardens, and flower cutting gardens. Allium flowers can also thrive in well-draining containers.
Soil, Light, Watering, and Fertilizing Considerations
Soil | Allium bulbs fare well in just about any type of soil as long as it is well-draining and never soggy. |
Light | Alliums grow best in full-sun locations. They can tolerate some shade, so a garden that receives partial sun/shade should be just fine. |
Watering | Alliums require only infrequent, moderate watering. In some areas, rainfall will provide plenty of moisture. It’s important that these plants do not sit in soggy soil. |
Fertilizing | Use a basic nitrogen-phosphorus-potassium fertilizer with slightly higher phosphorous content. Fertilize newly planted bulbs at planting and just after the first shoots emerge. Fertilize established plants in early spring before they sprout. |
Suitable Gifting Occasions for Allium Flowers

As they represent good fortune and prosperity, alliums are the perfect flower for wishing a person good luck at any endeavor or new start in life. This makes them a perfect addition to a birthday, graduation, or new career bouquet.
In-season during May and June, allium flowers also represent unity and make a wonderful choice for spring wedding flowers, too!
How to Care for Fresh-Cut Allium Flowers

For long-lasting, freshly cut allium blooms, trim when the blossoms are about 1/3 to 1/2 of the way opened. Always use sharp, clean pruning shears and cut stems away at an angle.
Once trimmed, hang to dry right away or plunge the stems into a bucket of cool, clean water immediately after removing them from the plant.
Before arranging in a vase, trim away any spent blooms and foliage that will be submerged in the vase’s water. Change the water every two to three days or more frequently to prevent a grilled-garlic-and-onion aroma from filling your house — unless you like the smell of a greasy spoon diner.
Enjoy Your Popular Perennials!
Hang it from your bedpost. Cut it for bouquets. Grow it in your kitchen garden for fabulous sautés. However you plan to use your ornamental or edible allium flowers, you’re sure to have a wonderful time cultivating these popular perennials in your gardens for years to come.
