Abstract

A new and distinct variety of Rugosa rose plant is provided which forms in clusters attractive single bright purplish-red blossoms having a strong fragrance. The blossom coloration is well maintained upon maturity. The plant exhibits a compact and typically broader than high growth habit with good vigor. Excellent resistance to Black Spot, Powdery Mildew and Downey Mildew is displayed. The very dense medium green to dark green foliage with a semi-glossy aspect contrasts nicely with the blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in the landscape and serves particularly well in small spaces and in mass plantings with minimal maintenance requirements.
