This variety has single, papery white blossoms that open from light pink buds and have contrasting yellow stamens. The heavily-scented flowers are followed by reddish-orange hips. It grows up to 6 feet high.
Noteworthy characteristics: Rugosa roses have thorny branches and attractive, distinctively wrinkled leaves. (The species takes its name from the Latin word rugosus, meaning "full of wrinkles".) They grow well in mixed borders, hedges, and as specimens. They are tolerant of harsh conditions, including salt spray, wind, and poor soil. 
Care: Grow in fertile, moist, well-drained soil in full sun or partial shade. Provide good air circulation and remove fallen leaves to help prevent disease. In late winter or early spring, prune lightly or back by up to one-third, reducing side shoots by one-half to one-third. To renovate, prune one in four or five shoots at the base.

This rugosa rose has flattened, symmetrical, semi-double, snowy white flowers with a spicy clove scent. The blooms display well against the shrub's dense growth of deep green foliage. Crimson-hued buds add even more color to this lovely variety. The blossoms don't drop cleanly, so deadheading is necessary.

'Polar Ice', also known as 'Polareis,' is one of the most impressive, vigorous, and densely growing rugosa rose varieties, exemplifying every positive trait of a rugosa rose. With clusters of double, slightly nodding flowers, the green buds of 'Polar Ice' open to creamy white blooms with shell pink petals and deeper pink centers. The flowers smell lightly of baby powder, and the new, glossy, lime green foliage smells like strawberries and sweet grass. The fall foliage of this exceptional rose turns the brightest, clearest yellow of all the rugosas.

A well-shaped shrub with dependable repeat bloom, 'Purple Pavement' has purple-red blossoms that are large, semi-double, and ruffled with a clear, bright, nonfading color and potent fragrance. It sports a good display of large, handsome hips and provides excellent fall foliage tones from yellow to maroon. A dependable performer, it is especially good for a late display, as fattening hips mix well with fall asters and other perennials featuring strong autumn hues.
