Have you ever wondered about that tall, leafy plant with purple flowers you often see along roadsides or in empty fields? You might be looking at alfalfa, an incredibly resilient and nutritious plant. With its long history, numerous health benefits, and remarkable nutritional profile, alfalfa deserves far more attention than it typically gets.
What is Alfalfa?
Historical Background
Alfalfa, scientifically known as Medicago sativa, has been cultivated for centuries. Its benefits were first observed by Arabian horsemen who noticed a significant boost in their horses’ energy when fed the plant. This early recognition led to alfalfa spreading across different parts of the world. Today, it’s recognized not just for its agricultural importance, but also for its use in natural and alternative medicine.
Botanical Classification
Belonging to the Fabaceae or legume family, alfalfa is related to beans, peas, and other legumes. Its scientific classification is:
| Kingdom | Plantae |
|---|---|
| Division | Magnoliophyta |
| Class | Magnoliopsida |
| Order | Fabales |
| Family | Fabaceae |
| Genus | Medicago |
| Species | Medicago sativa |
Synonyms
In some parts of the world, alfalfa is also known as “lucerne.”
Distinguishing Features
Height and Growth
Alfalfa plants can grow up to a meter in height. This tall stature, coupled with a deep root system that can extend over 15 meters, makes it highly resilient to drought and other environmental stresses.
Stem and Leaves
The plant stems are round at the base but become more angled towards the top. The leaves are alternate and scattered along the stem. Each leaf consists of three leaflets, somewhat similar to clover leaves, but more elongated and with sharp teeth on the edges.
Flowers
One of the distinguishing features of alfalfa is its flowers. They are grouped in clusters, each consisting of ten to twenty purple flowers. These flowers have an ordinary leguminous shape and resemble those of clover, making them relatively easy to identify.
Habitat
Alfalfa is most commonly grown by farmers for pasturage and forage but has also escaped into the wild. You might find it growing in meadows, near rivers, along roadsides and railroads, and even in urban vacant lots. The plant prefers disturbed habitats and is not typically an invasive species in high-quality natural areas.
Edible Parts and Their Uses
Leaves and Shoots
The leaves and young shoots of alfalfa can be eaten raw or cooked. They’re highly nutritious and can be dried for later use as tea or tossed into soups.
Seeds
Alfalfa seeds are often sprouted and added to salads, used in sandwiches, or consumed as a standalone snack. The seeds can also be ground into a powder and mixed with cereal flours for making bread and other baked goods.
Tea
An appetite-stimulating tea can be made from alfalfa leaves. This tea is often sweetened with honey to improve its flavor.

How to Identify Alfalfa
Stem and Leaves

Flowers
The flowers of alfalfa are one of its most distinctive features. You’ll find them in clusters, each containing ten to twenty purple flowers. These flowers have the typical leguminous shape, making them easy to identify if you’re already familiar with clover.
Roots
Alfalfa has a very deep root system, sometimes extending over 15 meters. This deep root system makes the plant particularly resilient in drought conditions.

Alfalfa in Agriculture
Animal Feed
Alfalfa is a popular choice for animal feed due to its high protein content and rich nutrient profile. It’s commonly fed to livestock like horses, cattle, and sheep.
Soil Health
Farmers also plant alfalfa to improve soil health. Its deep roots help to break up compacted soil, and as a legume, it can fix nitrogen in the soil, thus improving its fertility.
Environmental Impact
Soil Erosion
The deep root system of alfalfa helps to prevent soil erosion, making it a beneficial plant for marginal lands.
Biodiversity
While it prefers disturbed habitats and does not typically invade high-quality natural areas, alfalfa can support a variety of insects and animals, promoting biodiversity.
