Marigolds are bright plants in the genus Tagetes.

They are native to Mexico and Latin America. Many species grow well in almost any soil. Some types even handle dry ground well. These plants can be tall or short. Most have green leaves and colorful flowers. The blooms are often gold, orange, or yellow.

Some flowers even have dark red marks.

Many animals love these plants. Butterflies and bees visit them for nectar. Some caterpillars also eat them. In the wild, beetles help pollinate the flowers. This means they help the plants make seeds.

People use marigolds in many ways. In Mexico, they decorate graves for Day of the Dead.

In India, people use them for weddings and festivals. Some species are used for food. One type has a yellow part called lutein. This can be used to color foods like pasta or ice cream. Other types are used to make tea or herbs. Some people even use them to make perfume oil.

Marigolds are beautiful plants in the group called Tagetes.

They belong to a large plant family named Asteraceae. These plants can be small or quite tall. Some grow only 0.1 meters high. Others reach up to 2.2 meters. Most have green leaves that look like feathers. The flowers come in bright colors like gold, orange, and yellow. Some even have white or dark maroon marks.

They are very important to people and nature.

Many things happen to help these plants grow and live. Most species have a fibrous root system. This means their roots look like many tiny threads. These roots can release things called thiophenes. These substances can stop some other plants from growing nearby. This is why you should not plant them near legume crops. Many animals also help the plants. Butterflies and bees visit for nectar. In the wild, beetles help with pollination. This helps the plants make new seeds.

People have known about these plants for a long time. A scientist named Carl Linnaeus described the genus in 1753. The name Tagetes comes from Etruscan mythology. It refers to the god Tages, who was born from plowing the earth. The name might mean the plants grow easily every year. This happens from seeds or from stems that regrow. The English name marigold comes from "Mary's gold." This name honors the Virgin Mary. It was first used for a different plant in Europe.

There are many specific types of marigolds to know. Tagetes erecta is often called the African marigold. Tagetes patula is often called the French marigold. These flowers are used in many ways around the world. In the European Union, a part of Tagetes erecta called lutein is used as food color. It can color pasta, ice cream, and even mustard. In the United States, these extracts are used for animal feed. One species, Tagetes minuta, is used to make perfume oil. It is also used as a herb in Peru and Ecuador.

Marigolds are a big part of many cultures. In Mexico, Tagetes erecta is used for Day of the Dead.

In India, people use them for weddings and many festivals. They are sold in markets for daily rituals. In Ukraine, these flowers are a national symbol. They are even mentioned in songs and poems. Some people use Tagetes lucida to make a sweet tea. Others use Tagetes minuta to make a dish called ocopa. These plants connect many different people across the globe.

The genus *Tagetes* includes about 50 species of plants. Most are annuals, which means they live for one growing season. Others are perennials, meaning they live for many years. These plants belong to the Asteraceae family. In English, most people call them marigolds. They are native to Central and Southern Mexico and several Latin American countries. Some species have moved to other parts of the world. One specific species, *Tagetes minuta*, is considered a noxious invasive plant in certain areas.

These plants vary significantly in their physical size. They can grow as short as 0.1 meters. Some species can reach a height of 2.2 meters. Most have green leaves that are pinnate, which means they are divided into smaller leaflets. The flower heads usually measure between 4 and 6 centimeters in diameter. These blooms come in colors like gold, orange, yellow, and white. Many flowers also show maroon highlights. The flower heads typically contain both ray florets and disc florets.

Marigolds use a fibrous root system to grow. This type of root consists of many thin, thread-like strands. These roots exude substances called thiophenes. These chemicals have antibacterial properties. Because of these thiophenes, you should not plant marigolds near legume crops. Most species grow well in many types of soil. Many horticultural varieties prefer soil with good drainage. Some cultivars are also very tolerant of drought, which is a long period without rain.

History and naming provide interesting connections to the past. Carl Linnaeus described the genus *Tagetes* in 1753. The name *Tagetes* likely comes from the Etruscan god Tages. In mythology, Tages was born from plowing the earth. This name may refer to how easily these plants return each year. They can grow from seeds or from stems that regrow from a stump. The English name, marigold, comes from "Mary's gold." This name honors the Virgin Mary. It was originally applied to a different European plant called *Calendula officinalis*.

There are several distinct types of cultivated marigolds. African marigolds usually refer to hybrids of *Tagetes erecta*. French marigolds usually refer to hybrids of *Tagetes patula*. Many of those were developed in France. Signet marigolds are hybrids derived mostly from *Tagetes tenuifolia*. These different varieties are used for many specific purposes. Some are grown for their beauty, while others are used for food or medicine.

Marigolds have many important uses in industry and nature. The florets of *Tagetes erecta* are rich in a carotenoid called lutein. This is an orange-yellow pigment. In the European Union, lutein is used as a food colorant (INS number E161b). It colors foods like pasta, margarine, mayonnaise, and ice cream. In the United States, these extracts are approved for use in animal feed. In nature, marigolds support many animals. They are food for caterpillars like the dot moth. They also provide nectar for butterflies and bumblebees.

Cultural significance varies widely across the globe. In Mexico, *Tagetes erecta* is used for Day of the Dead celebrations.

In India and Bangladesh, they are used for weddings and festivals like the turmeric ceremony. They are even sold in markets for daily rituals. In Ukraine, varieties like *T. erecta* and *T. patula* are national symbols. They appear in local songs and poems. In South America, *Tagetes minuta* is used as a culinary herb called huacatay. It is used to make a potato dish called ocopa. Other species, like *Tagetes lucida*, are used to make medicinal teas.
