Collard is a type of green plant.

It is part of the kale group. These plants have large, dark-green leaves. People grow them to eat as a vegetable. Collards grow on an upright stalk. These stalks can grow over two feet tall. Some types can even reach six feet!

Collards are very good for you. They have a lot of vitamin K. They also have vitamin A and vitamin C. The leaves taste better after the first frost. This is when the cold weather hits.

People around the world eat collards in different ways. In East Africa, people call them sukuma wiki. They often cook them in oil with onions. In Portugal, they make a soup called caldo verde. This soup uses thin strips of the leaves.

In the United States, they are a famous food in the South. Many people eat them on New Year's Day. They often eat them with cornbread. This helps them soak up the tasty broth. This broth is called pot liquor.

Collard is a group of leafy green plants used for food. These plants belong to the same species as cabbage and broccoli. Scientists call them part of the Acephala Group, which means "without a head." This is because collards do not have a tight core of leaves like a cabbage does.

This open shape helps them handle humid weather very well. They are also less likely to get sick from fungal diseases. People have grown these plants for food since classical antiquity. They are a very important crop in many different lands around the world.

Growing collards is a step-by-step process that depends on the weather. The plants grow on an upright stalk that can reach two feet tall. Some Portuguese types can even grow up to six feet!

The leaves are often harvested before they reach their maximum size. Picking them early helps keep a good texture for eating. The leaves actually taste better and have more nutrients after the first frost hits. This is because the cold weather changes how the plant grows. Farmers must also watch for tiny pests called nematodes that live in the soil.

History shows how much people value this plant. In the United States, many different types were grown long ago. As people moved to towns after World War II, the number of types grew smaller. Only five varieties are commonly grown now, but many seeds are kept safe in government collections. In the American South, collards are a symbol of culture and identity. During the time of slavery, they were common in kitchen gardens. They were useful because they could survive a hot summer or a cold winter.

Different places have special names and ways to eat collards. In East Africa, they are called sukuma wiki and are often cooked with onions. In Kashmir, the plant is known as haakh and is used in many meals. People in Brazil and Portugal enjoy types like couve manteiga. They use these leaves to make a green broth soup called caldo verde. In the United States, people often eat them on New Year's Day. They serve them with black-eyed peas and cornbread to represent wealth. They even use the tasty broth, called pot liquor, to soak up the corn.

Collards are a powerhouse of nutrition for the body. They are mostly made of water, but they hold many vitamins. A single serving provides a huge amount of vitamin K. They are also rich in vitamin A, vitamin C, and manganese.

You can find them in many different forms, from fresh leaves to fermented sauerkraut. Whether they are stewed with meat in Montenegro or served with rice in Kashmir, they are a staple food. It is amazing how one plant can be so important to so many different people.

Collard is a group of loose-leafed plant cultivars belonging to the species Brassica oleracea. This same species includes other common vegetables like cabbage and broccoli. Collards are classified as part of the Acephala Group, which is often called the kale group. The name Acephala comes from a Greek word meaning "without a head." This refers to the plant's lack of a close-knit core of leaves. Unlike cabbage, which forms a tight head, collards have an open structure.

This specific growth habit makes them more tolerant of high humidity. It also makes them less susceptible to various fungal diseases.

The physical structure of the plant varies depending on the specific cultivar. Most collards grow on an upright stalk that reaches over two feet in height. Some Portuguese cultivars are even larger, reaching up to six feet tall. They are considered biennial plants, meaning they complete their life cycle in two years when winter frost occurs. However, some varieties may behave as perennials in warmer regions.

For the best texture, farmers often pick the leaves before they reach their maximum size. At this earlier stage, the leaves are thicker and require different cooking methods than older leaves.

Cultivating collards involves managing several environmental factors and biological threats. The plants are commercially grown for their thick, slightly bitter, edible leaves. These leaves are available for consumption year-round. However, they are often tastier and more nutritious after the first frost of the season. Growers must also protect the plants from various soil-dwelling pests known as nematodes. These are microscopic worms that can cause significant damage to the crop.

For example, the sting nematode (Belonolaimus gracilis) and the awl nematode (Dolichodorus spp.) act as ectoparasites that injure the plant. These pests can cause stunted growth, wilting, and chlorosis, which is the yellowing of plant tissue.

Nematodes present several different challenges to a healthy collard crop. The sting worm species Belonolaimus longicaudatus is particularly devastating to seedlings and transplants in Georgia and North Carolina. In sandy soils, as few as three nematodes per unit of soil can cause significant yield losses. Other species, like the stubby root nematodes (Trichodorus and Paratrichodorus), feed near the tips of the plant's taproots. This feeding prevents proper root elongation and creates tight, swollen mats of roots. Additionally, root knot nematodes (Meloidogyne spp.) can cause deformations called galls. These galls prevent the plant from taking up necessary water and nutrients, leading to wilting and stunting.

Collards provide significant nutritional value to the human diet. Raw collard greens consist of 90% water, 6% carbohydrates, and 3% protein, with negligible fat content. They are an exceptional source of vitamin K, providing 339% of the Daily Value (DV) in a single serving. They are also considered rich sources of vitamin A, vitamin C, and manganese, providing 20% or more of the DV. Furthermore, they serve as moderate sources of calcium and vitamin B6.

Because of this density of nutrients, they have been a staple in many global diets for centuries.

Historically, the use of collards has deep roots in many different cultures. In Europe, references to these plants exist in Greek and Roman history dating back to the 1st century CE. In the United States, collards are a vital symbol of Southern and African-American culture. During the era of slavery, they were common in kitchen gardens because they could withstand both summer heat and winter cold. In the Appalachian region, people often grow cabbage collards, which have yellow-green leaves and a partial heading structure. This differs from the dark-green, non-heading types found in the coastal South. Even today, various festivals and museums celebrate the cultural importance of the plant.

Culinary traditions for collards are diverse and reflect local ingredients. In East Africa, they are known as sukuma wiki and are often sautéed with onions and salt. In the Kashmir Valley, the plant is called haakh and is frequently served as a simple soup with rice. Portuguese and Brazilian cuisines utilize cultivars like couve manteiga or couve tronchuda. These are often used in the popular Portuguese soup called caldo verde, or "green broth."

In the Southern United States, collards are traditionally eaten on New Year's Day alongside black-eyed peas and cornbread to symbolize wealth for the coming year.
