Easy care, with a bushy habit, shrub roses are ideal for grouping together for stunning, flowering hedges. Knock Out Roses are some of the most popular hedge rose types available on the market today. They provide months of color with very little maintenance. Like other rose varieties, shrub roses bloom from late spring to early fall and usually grow in zones 5-9. They perform best when planted in full sun to partial shade. Low maintenance and with good disease resistance, shrub roses are usually lower growing than other rose varieties.
