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.

Apart from a handful of species found in South America, all species from the Allium genus are native to the northern continents.

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

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.

Soil, Light, Watering, and Fertilizing Considerations

SoilAllium bulbs fare well in just about any type of soil as long as it is well-draining and never soggy.
LightAlliums grow best in full-sun locations. They can tolerate some shade, so a garden that receives partial sun/shade should be just fine.
WateringAlliums 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.
FertilizingUse 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.

How to Care for Fresh-Cut Allium Flowers

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.
