[Letter of December 17, 1894 by Rudolf Geschwind on hybrid caninas]
...Already my first trials were crossings between Canina and Tea. Let us see what came out of it:.....
B. Mother Tea, father Canina.
Cyclop, enormous growth, beautiful smooth wood, scattered prickles, habit of Gloire de Dijon or Mad. Bérard. Blooms in clusters, well double and fine form, flat cup form, carmine-red, once-blooming; has abundant seed.
