PATENT OFFICE son & Perkins Com Application November 1 1 Claim.

The present invention relates to a new and distinct variety of rose plant, the result of a definite effort primarily to impart new vigor into the cut flower type of rose and at the same time reinforce, so to speak, the color of its bloom.

I have found that as a result of the hybridizing, not only were the foregoing objectives achieved, but an entirely new type, or strain, of forcing rose has been produced. Furthermore, extensive trials have demonstrated that this new rose forms an important addition to the garden rose line as it retains outdoors the characteristics and features which distinguish it under glass.

The purpose of selecting for its pollen parent the variety Federico Casas, a second generation seedling of Frau Karl Druschki (Pernetiana seedling x (Frau Karl Druschki x Rayon dOr), was to obtain the advantage of the exceptional vigor, upright habit and rich pigmentation which characterize this known rose while the seed parent Joanna Hill was selected because it is today the most used among yellow forcing roses.

The result of this cross exhibits as its main character the extremely long, slender streamline bud which under intensive greenhouse culture may reach up to three inches in length and sheathed in long sepals generally forming a bonnet above the bud branching like anthers.

In color, the bud is a combined rich gold and saffron, very lasting and changing but little, the petals being very thick and resembling kid leather in toughness.

The foliage of this new variety is also distinct and of a new type, rather elongated, thick and of a deep flat green. The foliage is also plentiful and the nodes between leaves very short.

The production of commercial flowers under glass has been found to be very large, exceeding that of the well-known Talisman, and this from the commercial standpoint lends extreme value to the new variety as revolutionary in the yellow cut rose industry.

From several years of testing and experimentation, the characteristics herein set forth have been demonstrated to be fixed in asexual propagation.

The following is a detail description of the new variety, reference to color according with the Gravereaux color chart:-
