- 1 Claim.

The present invention relates to a new and distinct variety of large flowered polyantha rose plant of the floribunda class, resulting from crossinga Goldilocks rose and a rose of the Holiday variety.

This new variety is unique because of its interesting habit of flowering, speaking with reference to the fact that the flowers change quickly from one color in the bud stage to another color as it opens, then toga still different color when open, and finally finishing of another. color. There is no accounting for this mutation, so far as therecent forebears of this variety are concerned and certainly not as regards the immediate parents.

Since the flowers grow in clusters and the flowers of each cluster develop at different times, the interesting phenomenon of color change continues for a long period of time, and since all the colors appear at once to the viewer as a combination it is difiicult to believe that this array of contrasting blooms could exist .on one and the same bush of this variety.

In general color terminology, each bud is golden yellow, the center bud of each cluster opening first and becoming rose-pink as the petals unfurl. Gradually the rose-pink deepens until the color becomes deep red. While the first loud in any cluster is passing through these stages, other buds are gradually developing, each to move'through the same color sequenceyellow to lemon to pink to red.

I was led to make the cross above referred to for the purpose of improving some of the characteristics of the two-tone variety Holiday, employing to this end, one of the best known new yellow roses Goldilocks as the seed parent. This cross did result in an improved'rose but also produced the complete mutation of color characteristics having no relation or similarity to those of the antecedents of this new variety, as before premised.

Another very desirable characteristic of this new variety is the lasting quality of the original flowers which hang on, without imparting a detrimental appearance, for several days.

Among other important characteristics of this new variety of plant may be included its vigorous growth and habit of producing many flowers, in clusters (25 to 30 buds), much above the average floribunda known to the trade.

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

The accompanying drawing illustrates specimens of this new variety showing the flowers at their different stages of development from bud to fully open bloom and the color mutation at the respective stages through which each bud moves.

This new variety was asexually reproduced at Newark, New York, by budding.
