Difference - rosa rugosa species v. rosa rugosa rubra

Need help from the experts, please! This weekend I bought rosa rugosa species in a pot from a nursery. It was on sale!!!! It is a healthy-looking medium-big bush, with great foliage. It had bloomed, and has a couple very spent blooms to prove it. The tag said it gets 3 ft tall - but I live in Maryland, near DC and we are Zone 6b/7a, which i more moderate than some locations. (Also hot and humid, so a rosebush I do not spray for blackspot or powdery mildew is welcome!) How big does rosa rugosa rubra get? Is there much difference in the bloom vs. rosa rugossa rubra? There are several nice rosa rugosa rubra and rosa rugosa alba bushes at National Arboretum, if anyone wants to see big established bushes. However, that garden does not have Rosa Rugosa species, so not sure how it differs. One book said Rubra is redder and species is dark pink or mauve. Is that so? Also how tall does r. rugosa species get? Finally, is it really true that one does not spray it? Thanks! Kathy
