The present invention relates to a new and distinct variety of rose plant, resulting from a cross'of the known varieties Charlotte Armstrong (Pl. Pat. #455) and Night, both of which produce flowers in the red range of colors. v This new Variety, as far as color characteristic goes, more nearly approaches that of the variety Mirandy (Pl. Pat. #632), but it differs importantly therefrom in that its bud is much more slender and its blooms are composed of about half as many petals-therefore having a much different appeal than Mirandy. These differences, more particularly pointed out hereinafter, have a decided practical or commercial value. That is to say, because of its slender bud, the new rose opens up much better in cool atmospheric conditions, than Mirandy, while on the other hand, the latter is able to better withstand extreme heat, so that each variety has its own adaptability to different locations or climates.

Another advantageous difference is found in the fact that in the present rose, the foliage is more abundant, and while more susceptible to mildew, itis more resistant to Orange Rose rust. Furthermore, its fragrance is much more mild and of a spicy character, in comparison with the very heavy, sweet fragrance of Mirandy. Comparing this new variety with its parents, it may be noted that the wood and stems thereof resemble more nearly those of its seed parent, butit does not resemble the latter in any other respect except toa slight extent in its open-flower form. It has a flower with more substance and better lasting quality than that of its pollen parent.

Because of a greater degree of rust resistance, as before mentioned, this new rose is better suited to coastal planting, under the influence of fog, than either Night or Mirandy, but it is not as well suited as Mirandy to inland areas where the heat is more severe during the summer, although it is superior in such areas to the variety Night. v

This new rose is characterized by its habit of producing more than one flower to a stem during the spring and early summer blooming period and by the production of only one flower to a stem during the late summer and fall blooming seasons, although the plants produce approximately the same number of blooms in the fall as in the spring season. Its adaptability for garden decoration uses serves to break the known scarcity of satisfactory garden varieties in the very dark red color range.

The drawing depicts a specimen of this new 1 Claim. (CI. 47-61) variety, its foliage and blooms in the bud, halfopen, and full-open stages.

Asexual reproduction shows that the characteristics hold true through succeeding propagations.

The following is a detailed description of the new variety, all references to color being in accordance with the R. F. Wilsons Horticultural Colour Chart, except where indicated to be in according with Ridgways Color Standard and Nomenclature:

This description of a newly opened flower was made from a rose grown outdoors in the month of October, 1945, at Ontario, California, in cool, cloudy weather:
