Some people eat the seeds. They make flour or porridge. They even make beer.

This grass can grow in yards. It is often called crabgrass. It grows well in thin grass. It likes little water.

One plant makes many seeds. It can make 150,000 seeds! The seeds grow in late spring.

The grass dies in the fall. This leaves empty spots in the lawn. New seeds grow in those spots. It is a busy plant.

Many people use these grasses for food. One type is called fonio. Fonio is a staple crop in parts of Africa. You can eat the seeds in many ways. People toast them or grind them into flour. They can also make porridge or even beer.

In North America, some types are called crabgrass. These plants can be a problem in lawns. They grow well in thin grass. They like areas with little water or food. One plant can make 150,000 seeds in one season! The seeds grow in late spring. They spread out in a circle. The grass dies in the autumn. This leaves big empty spots in the lawn. New seeds grow in those spots the next year. A healthy lawn needs water and food to stay strong.

Digitaria is a group of plants in the grass family. These plants grow in warm and tropical places. Some also live in cooler areas. You might know them by other names. People call them crabgrass, finger-grass, or fonio. The name Digitaria comes from the Latin word digitus. This word means finger. This is because the plants have long parts that look like fingers.

Many of these grasses are very useful for food. The seeds of fonio are very important. Fonio includes species like Digitaria exilis and Digitaria iburua. These are staple crops in many parts of Africa. People can eat the seeds in several ways. They can toast the seeds for a snack. They can also grind them into a fine flour. Some people make porridge or even beer from them.

In North America, some species can be tricky. Large crabgrass is also called hairy crabgrass. Another type is called smooth crabgrass. These plants often grow in lawns and gardens. They are considered weeds by many people. They grow best in lawns that are thin. They like spots with little water or fertilizer. They also like soil that does not drain well.

Crabgrass has a very fast way of growing. One single plant can make 150,000 seeds in one season. The seeds start to grow in late spring. They spread out in a wide circle. They grow faster than the grass in a healthy lawn. In the autumn, these plants die off. This leaves large empty spots in the grass. These spots are perfect for new seeds next year.

It is helpful to know how to care for a lawn. Using chemicals to kill weeds is one way. However, biological control is often a better choice. Crabgrass is often a sign of a weak lawn. It shows that the lawn needs more water. It also shows that the lawn needs more fertilizer. A healthy lawn can outcompete the crabgrass. This happens because the crabgrass dies every autumn.

Digitaria is a large genus of plants within the grass family, known as Poaceae. These plants are found in many different environments around the world. They thrive in tropical and warm temperate regions. However, they can also grow in subtropical and cooler temperate areas. Most members of this group are monocotyledonous plants. This means they are slender plants that grow from a single seed leaf. Some species are annuals that live for one season. Other species are perennials that live for many years. They are often used for forage, lawns, or pastures.

The name Digitaria comes from the Latin word "digitus." This word translates to "finger" in English. Scientists chose this name because of the plant's unique structure. The plants produce long inflorescences, which are flower clusters. These clusters look like long, spreading fingers. This distinct shape helps researchers identify them in the field. These finger-like structures carry the seeds that allow the plants to spread.

Many species in this genus are vital for human nutrition. Fonio is a major example of a useful Digitaria. It includes species such as Digitaria exilis and Digitaria iburua. In many parts of Africa, fonio serves as a staple crop. This means it is a primary food source for many people. The seeds are very versatile for cooking. People can toast the seeds or grind them into flour. They can also make porridge or even ferment the seeds to produce beer. Beyond humans, these plants provide decent nutrients for cattle forage.

In North America, certain species are viewed as garden pests. Large crabgrass, also called hairy crabgrass, is a common species. Another common type is smooth crabgrass, or Digitaria ischaemum. These plants often appear as weeds in lawns and gardens. They grow most successfully in lawns that are thin or weak. They prefer areas that receive very little water or fertilizer. They also thrive in soil that is poorly drained. In these conditions, they can quickly take over a space.

Crabgrass has a very efficient method of reproduction. A single plant is capable of producing 150,000 seeds in just one season. This high number allows them to spread rapidly. The seeds germinate during the late spring and early summer. As they grow, they expand outward in a circle. This growth pattern allows them to outcompete domesticated lawn grasses. When autumn arrives, these annual plants die off. This death leaves large voids, or empty spaces, in the lawn. These empty spots provide the perfect area for new seeds to germinate the following spring.

Managing these plants requires understanding why they appear. Many people use herbicides to kill crabgrass in their yards. However, biological control is often a more preferable method. This is because the presence of crabgrass is often a symptom of a problem. It shows that the lawn itself is not healthy. The crabgrass thrives because the lawn lacks proper watering or fertilization. If a lawn is restored with enough nutrients and water, it can outcompete the crabgrass. A healthy lawn grass will eventually win the competition.

There is a massive variety of species within the Digitaria genus. Some examples include Digitaria ciliaris, known as summer grass. Another is Digitaria eriantha, which is called pangolagrass or woolly finger grass. Other notable types include Digitaria brevicaulis and Digitaria villosa. This diversity allows the genus to exist in many different climates. From the desert-like Arizona cottontop to the tropical summer grass, these plants adapt to many roles. They serve as food, livestock feed, or challenging weeds depending on the environment.
