Rosa 'Zephirine Drouhin'

This relatively recent addition to the garden is a vigorous climbing Bourbon rose which is very free-flowering (from July through to September) and has the most wonderful scent. Although roses like to be in a sunny spot in fertile moist soil, this one will tolerate a north or east- facing position. Its stems are thornless - something Agatha Christie put to good use in a crime novel, enabling Poirot to deduce who the murderer was.
