ハマナス
"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. In parts of the US the fruits are also occasionally called beach plums, causing confusion with the plant properly bearing that name, "Prunus maritima".
