CLIMBING MULTIFLORA POLYANTHA ROSE PLANT Ralph S. Moore, Visalia, Calif.

Application June 22, 1948, Serial N 0. 34,392

1 Claim.

The present invention relates to a new and distinct variety of climbing multiflora polyantha rose plant, resulting from a cross of Etoile Luisant and Sierra Snowstorm, and particularly adapted for both out flowers and garden decoration purposes.

This new variety is characterized as to novelty by a number of distinctive features, among which may be noted the following:

The habit of blooming in both terminal and lateral clusters in extreme profusion in spring and early summer, followed by blooms in clusters intermittently and less heavily throughout the remainder of the growing season.

(2) Individual flowers combining the attractive form of the seed parent with the climbing trait of the pollen parent and in a shade of pink varying from the colors herein described and i1- lustrated to lighter and softer shades of pink at the peak of bloom and throughout the remainder of the growing season.

(3) Stems and canes with an almost complete absence of prickles, sufiiciently so that the prickles are diflicult to find even with a systematic search.

(4) Individual buds with form similar to the dwarf Pinkie, Plant Patent No. 712, suitable for florists use, particularly in making up corsages.

(5) A somewhat elusive fragrance in the flowers that is very strong at times for flowers of the Polyantha type and at other times only moderate.

(6) Relatively small but abundant foliage, glossy and somewhat leathery with more than average resistance to mildew,

Comparing this new variety with its seed parent, the points of distinction are that while Etoile Luisant is a dwarf rose, noticeably susceptlble to mildew and produces flowers of Scarlet Red, shaded Coppery, the present variety is a climber, strongly resistant to mildew and bears flowers of pink color.

Similarly, this variety differs from its pollen parent in that the flowers of Sierra Snowstorm are Cream and Yellow, are single, and foliage large in size, while this new variety bears pink double flowers with upwards of 38 petals, and has typically small foliage.

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

In the accompanying illustration, specimens of this new variety are shown at different stages of development, exemplifying the characteristics described hereinafter.

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