Tara: Origin, cultivation, benefits, and uses of the green gold of the Andes

In this blog, you'll discover what Tara is, where it comes from, where it grows, its botanical characteristics, how it is cultivated, the environmental and economic benefits it provides, its main industrial uses, and the role it plays in sustainable development in Peru and other Andean countries. Join me as we learn more about this remarkable native plant.

What is Tara?

Tara is a small tree or thorny shrub belonging to the Fabaceae family, the same botanical family as beans, acacias, and mesquite trees.

Scientific name of Tara

The scientific name of Tara is Caesalpinia Spinosa (Molina) Kuntze. However, some recent botanical publications also identify it as Tara Spinosa (Molina) Britton & Rose. Despite this, international organizations and technical standards continue to use Caesalpinia Spinosa, making it the most widely accepted name.

Names Tara is known by today

Depending on the country or region, this species is known by different names, including:

• Tara
• Taya
• Guarango
• Cuica
• Tara thorn
• Andean dividivi

Origin and distribution of Tara

Tara originates in the Andes of South America, particularly in territories that are now part of Peru. Since ancient times, Andean communities have made use of its pods, seeds, and other parts of the plant because of their natural properties and usefulness in a variety of traditional activities.

Today, Tara is found mainly in the following countries:

Why is Tara considered the "Green gold of the Andes"?

It is no coincidence that Tara is known as the "green gold of the Andes." This species combines three qualities that few forest plants possess at the same time: high economic value, an important ecological role, and significant potential to promote sustainable development. As a result, it has become a strategic resource for many rural communities.

Identifying a Tara tree

You can recognize a Tara tree by its small or medium size, its branches with small thorns, and its leaves, which are made up of many small green leaflets. During flowering, it produces yellow flowers arranged in clusters, while its fruit consists of flat green pods that turn brown as they mature. Its trunk is usually short, and its crown is open and irregular.

Characteristics of Tara

Let's start with the easiest features to identify.

Height

Under natural conditions, Tara generally reaches between 2 and 8 meters in height. However, some well developed specimens can exceed 10 meters when they grow in deep soils and have moderate access to water.

Important fact…

During its first few years, growth is usually slow. Factors such as altitude, soil type, rainfall, and agricultural management also directly influence the height the tree reaches.

Trunk

The trunk is typically short and sturdy, with branches often beginning relatively close to the ground. This characteristic helps the tree withstand the strong winds common in many inter Andean areas. In mature specimens, the trunk diameter typically ranges from 20 to 40 centimeters, although some very old trees can exceed these dimensions.

Bark

Over the years, the bark develops small longitudinal cracks across a surface that is brownish gray or dark brown. At the same time, it helps reduce water loss during dry periods and acts as a barrier against sudden temperature changes.

Branches

The crown has an irregular and fairly open shape. The branches are abundant and flexible and generally have short thorns. This characteristic is precisely what gave rise to the species name Spinosa, meaning "thorny."

Leaves

Each leaf measures between 10 and 20 centimeters in length and consists of several pairs of pinnae containing numerous small, oval, deep green leaflets. Thanks to this structure, the plant:

• Reduces water loss through transpiration.
• Reduces the impact of intense solar radiation.
• Facilitates air circulation between the leaflets.
• Improves photosynthetic efficiency in dry environments.

Flowers

Small and striking, the flowers are approximately 1 to 2 centimeters in diameter and have yellow coloring with reddish or orange hues. Flowering generally occurs between the end of the dry season and the beginning of the rainy season.
The main pollinators include:

• Native bees.
• Honeybees.
• Wasps.
• Some beetles.
• Other nectar-feeding insects.

Fruit

Once mature, the fruit does not open spontaneously. The pods are flat and slightly curved, with the following characteristics:

• 6 to 12 centimeters long.
• Approximately 2 to 4 centimeters wide.
• Relatively thick.
• Smooth surface.
• Green during development.
• Yellow during the intermediate stage of maturity.
• Reddish-brown or dark brown when they reach physiological maturity.

Seeds

Each pod normally contains between 4 and 8 seeds. These seeds are characterized by being:

• Oval shaped.
• Very hard.
• Dark brown or glossy black.
• Approximately 6 to 10 millimeters in diameter.

How long does Tara live?

Under natural conditions, Tara can live between 50 and 100 years, although some well-preserved specimens may exceed this range. When properly managed in plantations, the species:

• Begins producing pods between 3 and 5 years of age.
• Gradually increases its yield.
• Reaches peak productivity between 10 and 20 years of age.
• Continues producing for several decades.

History of Tara

The history of Tara is closely linked to the development of Andean civilizations. Long before the arrival of Europeans, communities living in the inter-Andean valleys were already familiar with the properties of this species and used its pods for a variety of everyday activities.

Tara in Pre-Hispanic cultures

The main documented uses include:

• Traditional leather tanning.
• Production of natural dyes.
• Leather preservation.
• Textile dyeing.
• Preparation of infusions used in traditional medicine.

Tara during the Inca Empire

With the consolidation of the Tahuantinsuyo, Tara became increasingly important within Andean agricultural systems. Its ability to grow on dry slopes and poor soils allowed it to become naturally integrated into a variety of agricultural landscapes.

Various uses of Tara during the Inca Period

• Protecting crops from wind.
• Marking agricultural plots.
• Conserving soil on sloped terrain.
• Providing firewood for household use.
• Serving as a raw material for producing natural dyes.

Tara during the Colonial Period

The arrival of the Spanish in the 16th century marked a new stage in the use of Tara. The tanning properties of its pods attracted the interest of workshops dedicated to leather processing, an activity that expanded considerably during the colonial period.

The importance of Tara today

In recent decades, Tara has gone from being a resource used primarily by local communities to becoming a strategic product in international trade.

Important facts about Tara you should know

Have you ever imagined having a Tara tree growing in your own backyard? Although it may seem like a simple plant, there are a few secrets to growing it strong and healthy. In this section, you'll learn how to plant it step by step, how its seeds germinate, and when to transplant it. Join me and discover how to bring this valuable Andean species to life!

Let's learn how to plant Tara step by step

Growing Tara begins with carefully selecting seeds, choosing well drained land, and properly preparing the soil. Although this species adapts to challenging conditions, it requires some care during its first few months to become well established.
