White Out Rose

Rosa 'Radwhite'

The Story

Plant Bio

Shrub roses are bred for landscape performance, combining hardiness and disease resistance with repeat blooming cycles throughout the growing season.

White Out is a compact, mounding shrub rose that produces abundant clusters of single, pure white flowers from spring until frost. It is self-cleaning, meaning the petals drop cleanly without the need for deadheading.

Uses & Benefits:

White Out provides a continuous display of clean, bright white flowers that illuminate the garden from spring to frost. Its compact, rounded habit is neat and tidy, making it suitable for both formal and informal designs.

This is a true low-maintenance rose, requiring no deadheading and exhibiting strong resistance to common rose diseases like black spot and powdery mildew. It is an excellent choice for beginner gardeners or those wanting roses without the fuss.

The single-form flowers are accessible to pollinators like bees, providing a reliable food source throughout the growing season.
