1 Claim. 1

The present discovery relates to a new and distinct variety of rose plant, originating as a sport of the known Gloire du Midi (Plant Patent No. 270).

This new rose belongs to the class of polyanthas and its claim to distinctiveness lies particularly in the intense scarlet color and in the fully double, polyantha-sized flowers; that is to say, the individual flowers of the plant are fully double, having twice as many petals as that of Gloire du Midi bloom. This full doubleness makes it much longer lasting and a much better rose for pot forcing. It is also primarily distinguished from its parent in the absence of the orange suffusion which characterizes the flower of the said parent variety. Further the individual flowers retain their color in the group, completing a uniform cluster until they finally drop oil.

Other primary distinctions of this new variety reside in its freedom of blooming and in the more or less commercial advantage of ease of handling ingreenhouse forcing, inasmuch as this variety always gives a good crop of flowers when forced in pots in the greenhouse.

In still other detail respects, the new variety differs from known roses in its class, as more specifically set forth in the following description of the rose, in which the color terminology accords with Ridgways Color Standard.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.
