There are colls. of this commonly cultivated species from FLEM, FRAN (EKY), LYON, TRIG (APSC) and elsewhere, but these are probably just persistent plants at old home sites and not truly naturalized. A coll. from SPEN (EK) may be from a wilder context. Some identifications are tentative; it appears that inflorescences sometimes have only 3 or 4 flowers, not 5-7 as in most descriptions. P. coronarius differs from pubescens sensu lato (including intectus) in its bark, which is reddish-brown and peels in the second year (versus usually gray and not peeling until 3rd year). Its flowers tend to be more fragrant. Well-developed leaves tend to be less hairy (mostly glabrous between veins) and to have relatively broad shape, distinguishing them from typical pubescens but resembling intectus.
