The string bean is an unripe, edible, common bean. The modern word bean comes from the Greek phasolion (bean).

The leguminous bean, a high-protein legume, is valued for its nutritional and gustatory qualities and is a dietary staple. With its diversity and use in culinary recipes in the modern world, it is difficult to imagine that originally European countries perceived this crop as an ornamental one. Asparagus beans were grown to decorate gardens and greenhouses.

Asparagus beans are called “asparagus beans” because their pods look and taste very similar to real asparagus, but are nutritionally even more useful than real asparagus beans.

History of Appearance and Proliferation

String beans, also called asparagus beans and green string beans, together with the other common bean varieties, belong to the common bean species.

The asparagus bean was first cultivated about 7000 years ago in Central and South America. It is mentioned in Chinese treatises of the second millennium B.C. It is not possible to determine the exact homeland of this crop. Historians are inclined towards the Americas, ancient Egypt and China.

Food bean seeds have been found as far back as Mexico. In burials from the 12th and 15th centuries in areas inhabited by Aztec and Mayan tribes.

The Spaniards were the first to get to know beans, followed by the Germans and the French.

In Europe, the bean started to be eaten in the 18th century. The crop has been known since the 17th century as “chickpeas” and in France it was called the French bean.

The main suppliers of beans on the world market today are India, China, Indonesia and Turkey.

There are dozens of varieties of string beans – curly, semi-curly and bushy.

How to Choose?

Pay attention when choosing green beans:

● Check that there are no spots on the pod;

● The colour of the pods should be uniform;

● The bean pods should have an even, light green colour and be flat;

● If the peas are very large, the beans are overgrown and have become coarse;

● there must be no rough fibres in the seams and no mechanical damage;

● Fresh beans are long, elastic but also quite flexible;

● When the pod is cracked, you should hear a loud “click”;

● When buying in a shop, check the integrity of the sealed packaging;

● Do not buy an overripe fruit with a hard skin.

When buying frozen:

● Pay attention to the expiry date;

● for the lack of ice in the bag, and that the beans are not lumpy – this indicates repeated defrosting.

Types and Varieties

The string bean is a shrub that is between 40 and 250 cm tall.

There are up to 50 different species.

The plant produces a variety of colours for the seeds inside the pod. Not only the seeds but also the unripe bean pods are edible because, unlike common beans, the pods do not have a parchment layer and rigid fibres.

When growing string beans, the bean is not allowed to fully mature in order to preserve the delicacy and juiciness of the pod. Nowadays, there are special varieties of asparagus beans that do not develop for a long time or have no parchment layer and fibres at all, the bean is round, with small to medium-sized seeds that taste like asparagus.

The pod flowers are mostly white or greenish and small. The ornamental varieties have been bred in various shades of red, purple, lilac and violet.

The shape, length and colour of the pods and beans also vary greatly. They can be almost flat, and rounded, straight or curved. The most common colours are green, yellow and purple. Less common are white, pink and mottled beans.

The main difference between the asparagus bean and the grain bean or peeled bean is that the pods can be eaten whole without removing the beans. If they become over-ripe whole, they are no longer suitable for eating.


Asparagus beans are divided into two main groups by plant type:

1. Climbing. The flexible stems reach a length of up to 3 metres and need to be tied to poles. Climbing species can also perform an ornamental function.

2. A bush variety. Predominantly low-growing. There are early- and mid-ripening varieties (45-60 days from seedlings to harvest) and mid-ripening varieties (55-75 days).

The bush beans come in several colours: green, light yellow, dark purple and mottled.  Varieties with green beans are the most popular as they have a familiar, classic appearance. Beans with yellow pods have a more appetising and unusual appearance. After cooking, the beans are slightly paler, but retain a slight yellowish tint. Dishes made with these beans look more exotic. The green and yellow asparagus beans do not differ significantly from each other in terms of taste. Different coloured asparagus beans make a very festive and unusual dish.

The purple-coloured asparagus bean pods lose their distinctive purple colour and change to a brownish-green colour when they are cooked. Mottled beans have very ornate pods with random splashes of purplish red on a pale yellow background. As it matures, the distance between the bright stripes and spots decreases and the pods become more red. Both the pods and the mature seeds are colourful.

Vegetable bean varieties can also be referred to as ‘sugared’ and ‘semi-sugared’:

Sugar bean pods are characterised by the round cross-section of the beans in the section; these pods are very fleshy and have a lot of jelly inside.

● In semi-sugar varieties, the pod is oval or flat in cross-section, and there is considerably less pulp (jelly). These varieties are usually referred to as all-purpose varieties because they are suitable for both grain and unripe cooking.

The main types of string beans:

Green asparagus beans have pods between 60 and 500 mm long. They are shaped like elongated cylinders or short sticks 7-13 cm high. Each one contains 3-8 beans. Green beans can have beans that are bright green, grey-green, green with purple lines or spots, and yellow.

The French species has dark green to light green pods up to 10 cm long.

Kenyan hybrids are distinguished by their small diameter (4-5 mm) and yellow-coloured seeds.

Chinese species reach 40-50 cm in length. Green beans. They are soft and tender pods. They can be eaten whole, with the skin on. It is a popular dish today. The pods are easy to prepare.

They boil quickly in salted water. Cut off the tough edges before boiling. Cooked pods can be frozen. They will retain all their healthy properties.

Purple beans-Dragon’s tongues. These are yellow-purple pods 12 cm long. They are also called Georgian beans. After boiling, the pods turn green. They can also be eaten raw. If the fruit is overgrown, remove the kernels and cook them separately.

Yellow wax beans. Good for soups, salads and stews. Suitable for eating raw. Can also be boiled, steamed, blanched or fried.

Flat bean is a subspecies of the asparagus hybrid. All varieties are green or yellow in colour. There can be up to 10 beans inside the pod.

● The bushy types of vegetable belong to the small green bean group. Their fruits are rounded, pea-like, and coloured white. The pods vary in colour from green to almost white. They are up to 6 cm long and have 4 to 10 peas inside.

The yield of the plant is high.

The pod is subdivided according to shape and size:

● The common type (common in all European countries) – the pod is up to 20 cm long. It can contain up to 10 beans.

● The ancient varieties of Vigna are bred in Asia. They reach a length of 60 cm to 1 m. Inside there are 100 seeds.

● The climbing bean stalks grow to a length of 3 to 5 metres. They are used for garden decoration. It needs good support because of the heavy weight of the pods.

● Another species grows on shrubs 40-50 cm high. It is unpretentious with regard to climatic conditions, can grow in almost any kind of soil and it ripens quickly.

The first three types include the asparagus bean and flat bean pod hybrids. They produce small bean fruits with a greenish-white colour.

Asparagus beans are great for canning.
