Very pleased with this hardy rose in Maryland, 7b. First season bare root from Palatine. She is in 19'' pot, has grown to a manageable 4.5', and is able to take the heat, humidity, and the rain with no issues. I imagine she could get a little taller if I put her in the ground. Palatine's 2-3' height description is a bit off but they do say it depends where you are growing it so keep that in mind when selecting this rose. What I love about Rosemantic Red most are the blooms which are long lasting. Pretty good black spot resistance but I do spray fungicide so can't comment for non spray gardens.
