Rosa Eglanteria is a type of wild rose that is also known as "sweet briar." There are many synonyms for this beautiful flower, including eglantine, briar rose, rosa rubiginosa, and hip rose. The term "eglantine" comes from the Latin word "aculeus," which means "needle," and refers to the plant's sharp thorns. Briar rose also derives its name from the plant's thorns. Rosa rubiginosa, on the other hand, refers to the rusty color of the plant's hips, which are the fruit that form after the flowers have bloomed. Finally, "hip rose" simply refers to the same fruit. Regardless of what you call it, Rosa Eglanteria is a lovely plant that has been used in herbal remedies for centuries.
