'Ena Harkness', one of the finest roses of our time, was raised by an amateur, Mr. Albert Norman, whose real job was connected with diamond cutting in Hatton Garden. But his success with 'Ena' was no fluke, for he also gave us 'Frensham', for many years the best seller among floribundas, and he later produced 'Isobel Harkness', 'Ann Elizabeth', 'Vera Dalton', and others.

David Ruston. I know some varieties can be wired if they have weak necks but 'Ena Harkness' is almost the only offender today.
