Rosa rugosa hybrids We no longer offer straight Rosa rugosa seedlings. Many wonderful old and new roses carry rugosa in their parentage (sometimes of an undetermined amount), and we have not observed these hybrids to be harmful to the environment. However the State of Maine legally requires us to include this statement: rugosa: Invasive species, harmful to the environment. Do not plant in coastal environments, especially on or near sand dunes. Alternatives: Bayberry and red chokeberry.
