'Agnes'  is one of the few yellow rugosa roses, and it epitomizes the finest rugosa attributes in both leaf and overall form. Doubled blooms give this selection an old-fashioned aspect, as does its delightful fragrance, which is reminiscent of antique roses. Bloom color changes somewhat with the temperature: in cool temperatures, the flowers are an apricot hue, but as the weather warms, they turn a soft yellow. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121

'Linda Campbell' is an unscented, true red rugosa rose. Attractiv, smooth-leaved glossy foliage and clusters of elegant buds open to bright blossoms. It grows in an upright habit  and makes a very nice addition to the back of a hot-color border. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121

Though not very well known, 'Dart's Dash' is  one of the best of the crimson double rugosa roses. 'Dart's Dash' has large blossoms with the spicy scent typical of rugosas and when blooming is done, the plant puts forth a marvelous display of showy hips. It establishes itself quickly and is a fine choice for a low hedge. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121

'Henry Hudson' has flattened, symmetrical, semi-double, white flowers with a spicy clove scent. The dense and deep green foliage makes a fitting backdrop for this selection's reddish buds and ensuing cream-colored flowers. The blossoms don't drop cleanly, so deadheading is necessary. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121

'Purple Pavement' has large, ruffled blossoms with a  purple-red color and strong fragrance. In the fall, the blossoms give way to large, handsome hips, and the foliage turns from green to shades of yellow and maroon. This shapely shrub with dependable repeat bloom it is especially good for a late display, when the hips appear alongside fall asters and other perennials with assertive autumn colors. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121
