It typically grows to a height of 10 to 30 centimeters and features trifoliate leaves, which are often marked with a distinctive light green or white pattern. The plant produces small yellow flowers that bloom from late spring to early summer. This species is native to Europe and parts of Asia but has also been introduced to other regions, including North America. Trifolium dubium thrives in a variety of habitats, such as grasslands and disturbed areas, and is often used as a forage crop due to its nitrogen-fixing properties.
