Dr. Georg Dieck christened this perfumed rose in 1889 when he introduced it from Bulgaria where the flowers are harvested and the attar distilled. Unfortunately, it is perhaps the habit either of taking short cuts or of laziness that has caused various parties since 1900 to speak or write of ‘Trigintipetala’ as ‘Kazanlik’. Die Gardenkunst, Bobbink & Atkins, Edward Bunyard, John Fischer, Botanica’s Roses, among others, and I myself, have been guilty of this misnomer. Other more careful rosarians (such as Graham Stuart Thomas and W. J. Bean), however, refer to it as “the rose from Kazanlik,” “the Kazanlik rose,” or “the rose of Kazanlik,” the distinction being the location, not the plant. Indeed, as Leonie Bell wrote in 1968 and reiterated in 1989, “We could well afford to drop ‘Kazanlik’ from rose nomenclature altogether since it has become synonymous not with var. trigintipetala but with confusion” and “‘Kazanlik’ [significantly she uses double quotation marks around that name] is a rose cursed with confusion. It is not the form of Damask known as ‘Trigintipetala.’” On the other hand, the Quest-Ritson team believes Kazanlik should be considered a grouping of similar Damask roses that would include ‘Trigintipetala’, ‘Prof. Emile Perrot’, and ‘Gloire de Guilan’. But that would seem to add to the confusion. If I were to speak of my Kazanlik rose and you of yours, and the roses were not the same variety, what a muddled misunderstanding might ensue. And it hasn’t helped matters that for most of the 20th century, the rose ‘Bella Donna’ has been sold by many a nursery as ‘Kazanlik’

Iwata et al. (2000) analyzed two Summer Damask varieties ('Kazanlik' and 'ork and Lancaster') and two Autumn Damsks ('Quatre Saisons' and 'Quatre Saisons Blanc Mousseux') and found no difference in their DNA profile using 24 RAPD primaers. Agaoglu et al. (2000) found no difference among accessions of R. damscena plants in Turkey using RAPD markers. Baydar et al. (2004) demonstrated that 15 R. damascena plants brought from 15 different plantations in Isparta province, which is the main rose growing region in Turkey, possess identical genotypes based on AFLP markers and nine microstaellite loci. Rusanov aet al. (2005a) characterized a total of 40 Damsk rose accessions of which 25 originated from Bulgaria (the collection of the Institute of Roses and Aromatic Plants, Kazanlik) using microstaellite arkers derived from Rosa wichurana and Rosa hybrida. The results showed that all analyzed 'Triginitipetala' accessions and the old garden Damask rose varieties 'York and Lancaster' and 'Quatre Saisons' (in confirmation of Iwata et al. 2000) possess identical genotypes. In Iran more than one genotype was found, but the genotype in the main production area was identical to 'Trigintipetala' (Babaei et al. 2007). In conclusion, it appears that the industrial production of rose oil in Bulgaria, Turhey, and to a great extent in Iran is based on a single genotype (and mutants thereof)....
The studies of Babaei et al. (2007) and Kiani et al. (2008) identified non-'Trigintipetala' genotypes, mostly in the mountainous northwestern part of Iran, with microsatellite alleles taht are not present in the Bulgarian and Turkish genotype. They are therefore not the result of self-pollination. This may suggest that the center of diversity may be in Iran, but detailed sampling of wild populations has not been carried out in the whole distribution area of the species.

Cluster analysis resulted in grouping of the 40 accessions ]of Rosa damascena] into nine distinct genotypes..... The main group consisted of 27 landraces that showed the same microsatellite profile. This group included all accessions from the main rose oil production sites of Damask rose in Iran [Isfahan]. The pattern of this group was identical to that of an accession from Bulgarian production areas. Rusanov et al. showed that all Bulgarian Damask roses are this genotype...

p. 68: ...identical phenotypes were found within OGR cultivars for R. xcentifolia L. 'Rubra' and 'Crested Moss' for 'Kazanlik', 'Quatre Saisons Blanc Mousseux' and 'York and Lancaster', and for 'Old Blush' and 'Viridiflora'.

p. 71: ʻQuatre Saison Blanc Mousseauxʼ, ʻKazanlikʼ, and ʻYork and Lancasterʼ are clustered as a single allelic phenotype, in agreement with Iwata et al. (2000). The first cultivar is a known sport of ʻQuatre Saisonʼ (selected by M. Laffay prior to 1837) and belongs to the Moss group (Beales et al., 1998; Cairns, 2000; Harkness, 1978); ʻKazanlikʼ and ʻYork and Lancasterʼ are two accessions of unknown origin morphologically similar to ʻQuatre Saisonʼ with deep pink and pink blended fl owers, respectively.

Kazanlik
Damask, No rebloom/Best fragrance/Tall broad-spreading canopies, heavy caned below and twiggy at the extremities, Keller?, 1689? ([provenence:] Huntington i.d.)
Puure pink flowers of typical Damask form, opening blowzy and fragrant from dark pink buds. Graham Thomas believes the true Kazanlik, from the attar fields of Bulgaria, is the rose called Professeur Émile Perrot.

Professeur Émile Perrot
Damask, No rebloom/Outstanding fragrance/Tall broad-spreading canopies, heavy caned below and twiggy at the extremities, Perrot, found 1931 ([provenance] Lowe; Perrot)
Large very shapely flowers set this fragrant rose apart from the blowsier Kazanlik, which is more fragrant still. Brought from the rose fields of Bulgaria by the French professor, this rose rightly attracts much attention in our garden.
