Bengale Rose Ducher
The variety of Bengale rose, whose portrait we publish, was obtained from a seedling after artificial fertilization, some say in 1865, others in 1869, by Mr. Ducher, the famous rosarian from Lyon. Contrary to those who pretend to be the owner of a hybrid of a carp and a rabbit, and who never reveal the father and mother, the good horticulturalist from Lyon shows us the remarkable seedling without telling us its parentage. As paternity research in Roses is not prohibited by law, we can try to figure it out. It would be easiest if we simply said it is a Bengale. However, considering its general appearance; its vigor that is much greater than most of its brethren among the Bengal roses; noticeably that it is the only one with a really strong white flower; taking account of its shiny leaves, its elongated bud, its petals unfolding in a spiral and its pronounced scent; we strongly suspect it took the intervention of a Tea Rose to give it all these qualities.

Another indicator confirms in our opinion that this rose is a hybrid of the Tea Rose: usually pure bred Chinas propagate easily by cuttings - like a weed- but the Ducher Rose lends itself poorly to this mode of propagation.

The Ducher Rose is a shrub of good vegetation with slender shoots, sometimes large and branching, light green, smooth bark armed with elongated, thin reddish prickles. Completely open, the flower is pure white, full, a little hollow at the center, however. This is a very good acquisition in this category of Roses ... Bengal roses, like Rosa semperflorens, are ever-blooming. No plant deserve this name better than these roses, flowering not even being stopped by the first frosts.

They are also referred to popularly as China roses: in effect, they were introduced from Canton to England in 1780 by the traveler Kée. It was not until 1800 that the Jardin des Plantes Paris had received the first examples, but it was a French amateur, Dr Cartier, who obtained the first varieties. Fréd. Burvenich père.
