[RAPD-PCR analysis was used to answer questions regarding the identity of numerous varieties of roses. Utilizing ‘Katie Bell’s Devonianthus’, it was determined that roses grown today as “Tradd Street Yellow” and ‘Devoniensis’ are very likely the real, original, ‘Devoniensis’.]
‘Devoniensis’ is a historic Tea rose variety introduced in its shrub form in 1838 by Foster and the nursery Prince & Company, and in the climbing form in 1858 by Pavitt and Curtis (Cairnes, 1993). Growers in England and California have what they believe to be the original ‘Devoniensis’, and sell it as such. The rose currently grown appears to match old paintings and descriptions, but there has been no solid historic link to prove it to be the “real” thing. Charles Walker (North Carolina State University, Raleigh) grew a rose that Katie Bell had gotten from her mother, who had always called it “Devonianthus,” undoubtedly a mispronunciation of ‘Devoniensis’. Since the original rose was introduced in 1838, the further back in time a person can be found growing the rose under its name, the stronger the evidence becomes to believe that the rose is correctly named. Katie Bell’s family had been growing that rose prior to 1884 (C. Walker, personal communication). Another rose found in Charleston, SC, by Ruth Knopf, called “Tradd Street Yellow,” appears to be identical to the California form of ‘Devoniensis’ obtained from Vintage Rose Gardens, Sebastopol, Calif. All three varieties were analyzed via RAPD-PCR. As shown in Fig. 3A, each band in “Katie Bell’s Devonianthus” was found in both “Tradd Street Yellow” and ‘Devoniensis’. This leads to the conclusion that all three are the same rose and supports the idea that the rose grown commercially is the real ‘Devoniensis’.
