Gaultheria procumbens (Wintergreen, Checkerberry)

This spreading rose grows to only 2 feet tall, making it an ideal groundcover for a steep bank or roadside. It produces fragrant, double, deep-pink blossoms from spring to fall.  

'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. -Suzanne Verrier, No muss, no fuss rugosa roses, Fine Gardening issue #121

This upright, suckering shrub bears creamy white, deliciously spicy clove-scented flowers in dense, upright spikes that last four to six weeks in July and August. It is more compact than the species. Flowers mature to spikes of dark brown capsules that provide winter interest. Its oval, glossy dark green leaves turn a pleasant yellow in autumn.

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.
