When it comes to Alliums, leeks and chives are two of the most popular. Both have a mild onion flavor and get used in various dishes, but there are some key differences between the two.

For one, leeks are much larger than chives. They have a long white stem with a greenish-white bulb at the end. On the other hand, Chives grow narrow, hollow green stems with small purple flowers.

Leeks are also milder in flavor than chives. When cooked, they become sweet and mellow, while chives have more of a sharp and pungent taste. Regarding cooking, leeks get used as a base for stews and soups. They can also be braised, grilled, or baked. Chives are perfect as garnish. Sprinkle some on top of salads, soups, and potatoes to add a delicious kick to the flavor.

So, what’s the bottom line? If you’re looking for a milder flavor, go with leeks. If you’re looking for something with more punch, go with chives.

Leek vs. Chive: Classification and Origin

Leek is a cultivar of the species A. schoenoprasum. This means that humans bred and maintained the plant to meet their desired characteristics. As a result, it’s different from varieties because they grow in nature without human interference.

Archeologists found specimens of leek in ancient Egypt sites, and wall carvings suggest Egyptians consumed leeks dating back to the second millennium BCE. In ancient Rome, people regarded leeks as superior to onion and garlic. Emperor Nero, the 5th Roman Emporer, believed it improved the quality of his voice, which led people to nickname him “leek eater.”  

On March 1st, the Welsh wear a leek in honor of King Cadawallader’s win over the Saxons. This day is known as St. David’s Day, and the leek plant is considered a Wales symbol.

Leek, chive, onion, scallion, and garlic belong to the same genus Allium. Chives (Allium schoenoprasum) are native to North America, Europe, and Asia. Europeans cultivated chives as far back as the middle ages and consumed chives for more than 5,000 years. The Romans believed chives could increase your blood pressure and relieve sunburn pain. In the middle ages, people called chives “rush leek” and cultivated them for ornamental and nutritional value.

Leek vs. Chive: Description

Leek is a vegetable that consists of long cylinder leaf sheaths. This is the edible part of the plant. Unlike the bulb onions develop, the leeks stem is fairly flat and grows between 2 – 3 feet tall, and its width is about 6 -12 inches. They can develop small bulbs but are significantly smaller than an onion.

They are hardy, true perennial plants. However, leeks can be biennial. The leaf shanks can vary in thickness and length. The leaves they produce are either yellow-green or blue-green leaves. The white and light green parts get eaten; however, the dark green parts have a ton of flavor.

Chives are herbaceous perennial plants that develop a bulb. They can grow between 10 – 15 inches tall, with bulbs around ¾ – 1 inch long and ½ inch broad. The stems are solid green, tubular-shaped, and hollow with a soft texture. Chives produce a beautiful pale purple flower with six star-shaped petals around ½ inch wide. Flowers are attractive to bees, but insects often find them to be repulsive due to their sulfur compounds.

It is easier to identify wild chives because they are some of the first plants to pop up in the spring, and you can spot them among the dormant grass. They look like a clump of grass, but you will see the hollow, cylindrical shape upon closer inspection.
