This study examined native populations of Rosa blanda and introduced, naturalized populations of Rosa rugosa along the St. Lawrence River estuary in Quebec and New Brunswick, Canada. Using both observable physical characteristics and genetic analysis, the researchers found that R. rugosa and R. blanda do hybridize freely. Their first-generation offspring look like a mixture of the two parent species and are probably fertile. The St. Lawrence River estuary is home to distinct types of R. blanda, such as R. rousseauiorum and R. williamsii, which might be threatened by hybridization with R. rugosa. R. rugosa's greater height, showier flowers, and greater abundance, the authors think, may make R. rugosa more attractive to pollinators, giving it a reproductive advantage over the native species rose. The authors conclude that the introduced R. rugosa may threaten native R. blanda and alter the dry coastal ecosystem of the St. Lawrence River estuary. The authors recommend more study to learn whether Rugosa hybrids planted in gardens are also a threat.

Hama-Nasu (Shore Aubergine) syn. =Hama-Nashi (Shore Pear) R. rugosa Thunb.
Murray. Syst. Veg. ed. 14:473 (1784)
Distribution: Hokkaido, Honshu
R. rugosa is distributed in the northern parts of Japan, mainly in coastal areas. This is the prefectural flower of Hokkaido, and there are some famous sights featuring Rugosa flowers on this island. We can also see this rose in Honshu, north of Chiba Prefecture on the Pacific coast, and north of Shimane Prefecture on the Japan Sea coast...The author has seen naturally growing R. rugosa in many different places. In Sado Island in the Sea of Japan, she saw a bush growing by the sea as if clinging to the rocky beach. On a beach in Hokkaido facing the Okhotsk Sea, it was blooming on a sandy stretch swept by cold winds. A beach which is constantly sprayed with sea water would not allow even this rose to survive, but it does not seem to mind a harsh wind from the sea. The author saw this rose beautifully in bloom where few other plants were seen growing.
It is famous as an ancestral rose of Hybrid Rugosas in European countries, and for long years, Japanese people have enjoyed its sweet fragrance, and also used petals and fruits of this rose for sweet preserves. In Akita Prefecture, the bark and roots of R. rugosa are sources of important dyes for dying traditional fabrics called 'Akita Ki-Hachijo' (Checkered Yellow Cloth from Akita).

R. rugosa... called the 'Japanese Rose' in the West, In Japan it is called 'Hama-nasu' or 'Hama-nashi' because Hama means beach or shore which is where it naturally occurs... Because its large fruits resemble an aubergine (eggplant) it is sometimes called nasu which is the Japanese term for this vegetable... in the areas of Japan where it is found, people speak with a nashi accent... its fruit resembles a Japanese pear, also called nashi... Carl Peter Thunberg (the Swedish botanist who introduced this rose to the West) called it the 'Ramanas Rose' which is believed to be a misinterpretation of one of the Japanese names... on his return to Europe he published his Flora Japonica 1784... it grows wild along the shoreline... In 1978 the Hokkaido local government made this rose their local symbol.
