Engelbert Kaempfer
The deutzias are fairly new to gardens: the exception, "D. scabra", was noticed in Japanese gardens by Engelbert Kaempfer (1712) and Carl Peter Thunberg (1784) but not actually seen in Europe till the 1830s; two-thirds of the species noted in the R.H.S. "Dictionary" were gathered in from the wild during the 20th century.
