Philadelphus purpurascens
12th June 2016
Philadelphus purpurascens F.1697
A species that is very close to P. delavayi. Introduced by Wilson from W.Szechuan, my plant claims (possibly erroneously) to be a George Forrest collection.

Another one that finally made it into the garden after too many years kicking around in a small pot.
