Rugosa species and hybrids
Rugosa [Rosa rugosa] are sturdy shrubs; very healthy and winter hardy. They are usually identified by their foliage, which is typically bright green and heavy textured with deep veining (rugosa). Their flowers vary from single to double and most varieties are rather informal in shape. Most Rugosas produce large, decorative hips that attract and feed birds in the fall and winter. They are very easy to grow and do well in poor conditions. One word of caution: rugosas do not like to be sprayed with chemicals.
Rosa rugosa rubra
Species, OGR. Natural selection from the species for red, 6X6'.
Large single blooms of deep pink with a purple cast, creamy stamens and
a strong fragrance.
Continuous bloom, largest single Rugosa bloom. Good fall foliage
color, excellent set of hips.
Rosa rugosa alba

Single white blooms set the standard for all the white Rugosa hybrids.
Creamy stamens,
continuous bloom, orange hips and dense deep green foliage. Excellent
as a tall hedge.
