p. 46: Tsarina of Light Origins: (R. lutea Persian Yellow × R. damascena Kazanlyk) × R. polyantha Clothilde Soupert “It has average growth, seldom reaching the height of three arshins; shoots a red-dark brown, dotted with a bit more thorns than the R. lutea, and the shape of the leaf and its segments is more circular, much wider and duller serrated, with more matte surface of the leaf plastins. Then, the foliage does not have a specific flavour as R. lutea’s leaves. Continuous abundant blooming, every single bloom stays not fading for a very long time... Blooms are full, double, of regular shape; bright silvery-pink colour, have an extremely strong and very pleasant fragrance. Harsh winters in our area this new variety stands without protection. During comparative experiments in distillation (in an arranged by me indoor apparatus) of the fl owers of this new variety and of Kazanluk oil-bearing rose it turned out that Tsarina gives a better distillate [rose oil - AA], both in quality and quantity.“ ”This is the first Russian oil-bearing rose.
