'Polar Ice' is one of the most vigorous and densely growing rugosa roses and features clusters of double, slightly nodding flowers. Green buds open to creamy white blooms with pink petals and deeper pink centers. The flowers smell lightly of baby powder, and the new lime green foliage smells like strawberries and sweet grass. In autumn, the foliage turns bright yellow.

'Wasagaming' (pronounced "wah-SAG-ah-ming") is a prolific bloomer that has the charm of the antique roses but with greater vigor and better growth habit. Cascading rich pink blossoms with an old-rose scent spill across the shrub. 'Wasagaming' will thrive in less sunny but bright conditions.

'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.

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.

'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.
