Breeder's notes:
This was given to me by Ralph Moore as a breeding plant. Date of breeding unknown, likely from the 1990's or earlier. Ploidy unknown but probably a tetraploid. It is extremely fertile as a pollen parent but not very easy to obtain seed from. Very easy to grow and thrives on neglect, its only real downfall is its susceptibility to Blackspot. However, it is never denuded by the disease and outgrows it quickly. The Spring flush is very impressive (see photos) but rebloom is sporadic at best after that. No fragrance.

This has potential as a breeding plant.
