Characteristics of Red Clover and Crimson Clover

Plant Description

Red clover and crimson clover are both members of the legume family, known for their ability to fix nitrogen in the soil. These clovers are herbaceous annual or biennial plants that typically grow to heights between 12 and 36 inches. They produce clusters of small, pink to purple flowers that bloom during the spring and summer months. The leaves of both clovers are compound with three oval leaflets, giving them a distinctive appearance.

Origin and Distribution

Red clover (Trifolium pratense) is native to Europe, western Asia, and northwest Africa. It has been widely naturalized in North America and is cultivated as a forage crop in many regions. Crimson clover (Trifolium incarnatum) is native to the Mediterranean region and is commonly used as a cover crop in the United States, particularly in the southern states. Both clovers are adaptable to a wide range of climates and soils.

Growth Habit

Red clover and crimson clover have similar growth habits characterized by a prostrate or semi-erect form. They have branching stems that create a dense foliage cover. Both clovers have a taproot system that helps them establish and access nutrients from the soil. They have a relatively short lifespan, typically lasting for one to three years.

Germination and Establishment

Red clover and crimson clover have different germination and establishment requirements. Red clover seeds have a hard seed coat that requires proper scarification or pre-treatment to improve germination rates. It prefers cool soil temperatures between 50 and 60 degrees Fahrenheit for successful establishment. On the other hand, crimson clover seeds have a soft seed coat and germinate more easily. They thrive in warm soil temperatures between 65 and 75 degrees Fahrenheit.

Differences in Appearance

Leaf Structure

While both red clover and crimson clover have compound leaves with three leaflets, there are slight differences in their leaf structures. Red clover leaflets are typically larger and broader compared to crimson clover. The leaflets of red clover are oval-shaped, while crimson clover leaflets are narrower and slightly elongated.

Flower Color

One of the most noticeable differences between red clover and crimson clover is their flower color. Red clover blooms with vibrant pink to purple flowers, adding a splash of color to the landscape. Crimson clover, as the name suggests, produces bright crimson or deep red flowers. The distinct flower color of crimson clover makes it easy to identify in the field.

Plant Height

Red clover and crimson clover also differ in their plant height. Red clover typically grows taller, ranging from 12 to 36 inches in height. On the other hand, crimson clover tends to be shorter, averaging between 12 and 24 inches. These height differences can impact the overall appearance and growth characteristics of each clover species.

Suitability for Different Climate Conditions

Cold Tolerance

Red clover exhibits better cold tolerance compared to crimson clover. It can withstand frost and freezing temperatures, making it suitable for cooler climates. Red clover can continue to grow and produce forage during the early spring and late fall when temperatures are lower.

Heat and Drought Tolerance

Crimson clover demonstrates greater heat and drought tolerance compared to red clover. It can withstand higher temperatures and periods of limited rainfall better than red clover. Crimson clover is often preferred in regions with hotter summers and sporadic rainfall.

Rainfall Requirements

Both red clover and crimson clover have similar moderate rainfall requirements. They thrive in regions with an average annual rainfall between 20 and 40 inches. Adequate moisture is essential for the establishment and growth of both clovers. However, crimson clover has a slightly higher tolerance for periods of drought compared to red clover.

Forage and Hay Production

Yield Potential

When it comes to forage production, both red clover and crimson clover have impressive yield potentials. Red clover typically produces higher forage yields compared to crimson clover, especially in cooler climates. Under optimal growing conditions, red clover can produce up to 4 tons per acre of high-quality forage.

Nutritive Value

Both red clover and crimson clover are highly nutritious forage options. They have a high protein content, ranging between 18% and 24%, which is essential for livestock growth and production. Both clovers also contain essential minerals and vitamins, including calcium, phosphorus, and vitamins A and E.


Livestock, particularly grazing animals like cattle and sheep, find both red clover and crimson clover highly palatable. The tender leaves and flowers of these clovers are eagerly consumed by animals. Their palatability contributes to improved livestock performance and increased forage utilization.

Soil Requirements and Agricultural Application

Soil Adaptability

Both red clover and crimson clover are adaptable to a wide range of soil types. They can tolerate soils with varying textures, including sandy, loamy, and clay soils. However, they prefer well-drained soils with good organic matter content.

pH and Fertility Preferences

Red clover and crimson clover have similar pH and fertility preferences. They thrive in slightly acidic to neutral soils, with a pH range between 6.0 and 7.0. These clovers benefit from adequate soil fertility, especially sufficient levels of phosphorus and potassium, for optimal growth and nutrient uptake.

Crop Rotation Benefits

Both red clover and crimson clover offer significant benefits when used in crop rotation systems. Due to their ability to fix atmospheric nitrogen, they enrich the soil with this essential nutrient. This nitrogen fixation reduces the reliance on synthetic fertilizers for subsequent crops, leading to improved soil health and reduced environmental impact.

Benefits for Livestock and Wildlife

Feeding Value

Red clover and crimson clover provide excellent feeding value for livestock. They offer a high-quality source of protein, energy, and essential nutrients. Livestock fed with these clovers experience improved weight gain, milk production, and overall health.

Forage Quality

The forage quality of red clover and crimson clover is exceptional, making them beneficial for livestock nutrition. They have high digestibility rates, ensuring that animals can efficiently break down and utilize the nutrients present in the forage. The high protein content and balanced nutrient profile enhance the overall nutritional value for livestock.

Wildlife Attraction and Forage

Red clover and crimson clover also play a role in attracting wildlife to agricultural areas. The attractive flowers of both clovers provide a nectar source for bees and other pollinators, supporting pollination and biodiversity. Moreover, the dense foliage cover of these clovers offers refuge and forage opportunities for small mammals and birds.

Potential Medicinal Uses

Herbal Properties

Red clover and crimson clover have long been recognized for their various herbal properties. Both clovers contain phytoestrogens, compounds that mimic the effects of estrogen in the body. These phytoestrogens have been used in traditional medicine to alleviate menopausal symptoms and support hormonal balance.

Traditional Medicine Uses

In traditional medicine, red clover and crimson clover have been used to treat a range of ailments. They have been employed as a diuretic, expectorant, and antispasmodic. These clovers have also been used to promote skin health, alleviate coughs and colds, and support overall wellness.

Potential as a Cover Crop

Nitrogen Fixation

One of the primary benefits of both red clover and crimson clover as cover crops is their ability to fix atmospheric nitrogen. They form a symbiotic relationship with nitrogen-fixing bacteria in their root nodules, converting atmospheric nitrogen into a usable form for plants. This natural nitrogen fixation reduces the need for synthetic fertilizers and improves soil fertility.
