Polyantha.  

White or white blend.  None / no fragrance.  17 to 25 petals.  Average diameter 1".  Small, double (17-25 petals), in large clusters bloom form.  Blooms in flushes throughout the season.  

Medium, upright.  Medium, semi-glossy, medium green foliage.  

Height: 30" to 3' (75 to 90cm).  

USDA zone 6b through 9b (default).  Can be used for container rose, garden or landscape.  Remove spent blooms to encourage re-bloom.  Spring Pruning: Remove old canes and dead or diseased wood and cut back canes that cross. In warmer climates, cut back the remaining canes by about one-third. In colder areas, you'll probably find you'll have to prune a little more than that.  

Produces tremendous sprays of pure white blooms on long stems.
