Rhododendron 'Double Winner', exact paratage?
I have been experimenting with hybrids of R. strigillosum to see if they can take the heat in my bucks county PA garden.
One of the hybrids that I have is 'Double Winner', a magnificent red
Does anyone know the full parentage of this hybrid? I can only find strig x unknown.
Likewise, I plan to try R. 'Peter Faulk', which is also listed as strig x unknown.
I have had success with several strig hybrids, but that has only been if one of the other parents has imparted the heat tolerance, such as Jean Marie de Montague, Maximum, R. yakushimanum.
I was told that Double Winner might be a cross between strig and Janet Blair, but do not see a hint of Janet Blair in the shrub.
My goal is to cross Double Winner with Harold Amateis, in anattempt to remove some of the 'blue' in the red of Harold, yet retain Harold's fantastic hardiness (from Maximum) and strig like foliage
Thanks for your help
