Some of the synonyms for wert clover include white clover, dutch clover, ladino clover, and shamrock. White clover is perhaps the most commonly used synonym for wert clover, as it accurately describes the appearance of the plant. Dutch clover is another popular term, as this species was first introduced to the United States by Dutch settlers.

Shamrock, while not technically a synonym for wert clover, is often used colloquially to refer to any clover with trifoliate leaves.
