The resulting offspring possess many desirable qualities that have made them a favorite among gardeners for centuries. Known for their profusion of clustered blooms, Polyantha Roses offer a breathtaking display of vibrant colors and delicate petals.

Another remarkable characteristic of Polyantha Roses is their exceptional disease resistance.

Pruning Polyantha Roses is also a straightforward process.
