Bobbink & Atkins were located in Rutherford, NJ through much of the twenties through the fifites, The basis for the extensive collection of rare and unusual roses was occasioned by the purchase of some 3K roses from the estate of a European collector. Bobbink was a Dutch immigrant described in an article by Nicolas in an ARA article (thirties) as one of three schoolmates who did well in the rosarian world, albeit in different aspects.

Reprinting below is the entire entry in the 1929 catalog:

COMTESSE PROZOR H.Gig. (P. Nabonnand, 1921) Very large-pointed buds and enormous saucer-like flowers of rich chrome-yellow, with a creamy undertone. A strong, robust climber.

This is the first of Nabonnand's new Hybrid Giganteas to get into American commerce. We cannot guarantee that Comtesse Prozor will be entirely hardy, but M. Nabonnand says that the young plants bloom only once a year but that when they are well established they bloom continuously. $1.50 each.
