Allister Stella Grey

This Noisette can be grown as a climber or free-standing shrub.  It is wonderfully healthy, and has exceptionally good rebloom.  The yellow and white blooms are charmingly irregular..sometimes a bloom will be half yellow, half white.  There are few thorns.  It could do well in a no-spray garden. 
Bred in 1894, rated as hardy from zone 5.
