A beautiful and very floriferous hybrid raised by N. G. Hadden of Porlock. A specimen was received by Kew from Mr Hadden in 1922 and nine years later it received an Award of Merit when shown at the Chelsea Show, May 1931. It bears fragrant flowers in April and May and, though rather tender, grows quickly into a large shrub. (Bean 1976).
