Maud through the roses

Found its name.
Rosa rugosa is widely used as an ornamental plant. It has been introduced to numerous areas of Europe and North America. It has many common names, several of which refer to the fruit's resemblance to a tomato, including beach tomato or sea tomato; others include saltspray rose, beach rose, potato rose and Turkestan rose.[2] Its fruit are sometimes mistaken for those of the beach plum – despite being entirely different in size, shape, color, texture and taste.

The sweetly scented flowers are used to make pot-pourri in Japan and China, where it has been cultivated for about a thousand years.
