1 Claim.

The present invention relates to a new and distinct variety of rose plant, of the Floribunda class, originated by crossing of a semi-climbing seedling and the 'well known climbing rose Doubloons (Plant Patent 152). The latter variety is characterized by its vigorous and hardy habit of growth, its production of large golden flowers, and spicy, clean fragrance.

It was the object of the present invention to incorporate as many of these desirable and valuable characteristics as possible in a rose of the Polyantha class and as a result of the cross aforesaid, this new variety displays a number of important improvements, among the primary of which is its exquisite composition of golden yellow or the bloom and attractive shiny dark green foliage, illustrated as nearly as possible to depict in the accompanying drawing.

For a Floribunda rose, it is notable for the permanence of its coloring, that is, the ability of the blooms to retain their color throughout all of the stages of their development, unlike previous similar varieties that show the yellow shade in the bud and partially opened flower only.

Another important feature of this new Floribunda is its rugged characteristic of producing flowers under extreme conditions of heat and drought.

In growth habit, this plant is of bush form with dense spreading foliage, quite resistant to blackspot.

The buds of this new rose are rounded in form, developing into fully petalled flowers, growing in rather flat clusters, and these flowers possess a moderate fruity fragrance.

The foregoing dominant characteristics of this.

new variety, among others referred to in the following detailed description, have been found to be established by asexual reproduction. (Color terminology accords with Ridgways Color Standard.)
