The generic name philadelphus, sister’s lover, is a tribute to the creator of the library of Alexandria, Pharaoh Ptolemy II Philadelphus, named after marrying his sister, a common practice in ancient Egypt. The sweet mock-orange comes from southeast Europe and nearby Asian areas. The sweet mock-orange with spikes, fuzzy deutzia or deutzia scabra, are species very similar to the previous and native to Japan.
Romero Zarco differenciates between sweet mock-orange and fuzzy deutzia. So Romero Zarco says on the deutzia scabra 'it is easily distinguished from the sweet mock-orange on traces left by the inflorescences. The species comes from Japan and is grown in Spain since 1833. Its generic name was given by Thunberg in honor of his friend Johan van der Deutz '.
And on the sweet mock-orange, philadelphus coronarius, it was precisely in Seville where it adopted its common name is Spanish. The Seville gardeners renamed it “celinda”, adapted from Castilian syringe or syrinx. The name passed in turn to a street of the city of Seville dedicated to this plant.
