In heraldry, the daisy, often called a marguerite in blazon, is usually understood as a symbol of purity, innocence, humility, and cheerful constancy. Its simple open form and bright appearance make it a natural emblem of youthful hope, honest character, and affection without ostentation, so it can suit families or institutions that wish to emphasize modest worth rather than grandeur. Because the flower returns year after year and is strongly linked with spring meadows, it can also suggest renewal, fertility, and a close bond with the countryside. In some contexts it carries a gentle religious resonance as well, since white flowers of this kind could evoke Marian purity in later Christian symbolism, though the daisy never acquired quite the fixed sacred status of the lily. As a heraldic charge, it often conveys a lighter and more personal meaning than martial symbols, and it may reflect family background, local landscape, or a preference for floral emblems associated with grace, sincerity, and enduring loyalty.

A particularly important heraldic use of the daisy appears in the form of the marguerite badge associated with royal and noble women named Margaret, since marguerite is the French form of the name. Margaret of Anjou famously used the marguerite as one of her personal badges, and Margaret Beaufort also employed the marguerite in her well-known badge tradition, making the flower a classic example of a heraldic rebus or name allusion rather than a merely decorative blossom. For that reason, the daisy in heraldry often points to identity, lineage, or dynastic association as much as to abstract virtue. It is more commonly found in badges, crests, and later personal or institutional heraldry than among the most ancient and widespread shield charges, and its exact style may vary from a naturalistic bloom to a more formal heraldic flower. In coats of arms and heraldic art, the daisy or marguerite most often represents purity, modesty, renewal, faithful love, springtime, and a traditional connection to the name Margaret.
