As its name implies, this Rose is rarely without flowers, and it is 
for its beauty and hardiness one of the most valuable acquisitions to 
our gardens. It was introduced into England in 1 789 by Gilbert Slater 
of Knots Green. He was an enthusiastic and successful gardener, and 
was the means of introducing into this country many rare plants, which 
he readily distributed amongst those of his friends who would cultivate 
them. It was through his generosity that this Rose was in a very 
short time to be found in most of the gardens in the neighbourhood of 
London.
