Shrub roses make a big impact in the garden and the landscape when they bloom during the summer months. These easy-care roses have a bushy habit, making them a top choice for grouping together as a flowering hedge. Most rose plants bloom from late spring to early fall and grow in zones 5-9. Like other rose bushes, shrub or hedge roses perform best when planted in full sun to partial shade and in well-drained soil. Most shrub roses are lower growing that other rose varieties—and they are available in an array of flower colors including red, yellow, purple, pink and white hues.
