About Rosa agrestis Savi
Rosa agrestis, commonly known as the small-leaved sweet briar, field briar, or fieldbriar, is a species of wild rose. It is native to Europe, where it grows mostly in southern Europe, and occasionally occurs as far east as the Caucasus. Different sources disagree on whether it is also found in northern Africa and Anatolia. Classified as a dog rose, it belongs to the subgenus Rosa, section Caninae, and subsection Rubigineae. It is a close relative of the sweet briar, Rosa rubiginosa, and strongly resembles that species, but differs in having smaller leaves, white to blush-colored petals, and very little scent from both its flowers and its leaves. While Rosa agrestis may be grown in cultivation, most gardeners prefer sweet briar for its scented foliage and pink flowers.
