PATENT OFFICE 1 Claim.

This invention relates to a new variety of rose, a wz'churaiana hybrid.

The variety was originally produced by crossing a variety wichuraiana, as the female or seed parent, with a hybrid, as the male or pollen parent, which was produced by crossing a variety "multiflora as the female parent and the variety "Rosa foetida bicolor as the male, or pollen, parent. It has been asexually reproduced true to form in considerable quantity.

The variety is extremely hardy and above average in disease resistance. It has been grown unprotected in the northern regions of the United States and appears to be hardy and adapted for growth, unprotected, throughout the United States generally and elsewhere throughout regions in the temperate zones. It can be grown protected in colder regions.

The plant is a strong climber attaining a height of fifteen feet or more.

The leaves are smooth, small in size, medium in quantity, and light green in color, comparable to Maerz & Paul Plate No. 22-L-9, and are almost totally hidden by the blooms during the blooming season. The leaves are resistant to mildew and black-spot.

The plant produces a superabundance of pure white flowers, which are saucer-shaped. They are borne in umbells and threes, often semipendant on slender, limber stems, beginning generally at one and one-half to two feet from the base of the plant. They are massed in great abundance and profusion upwardly therefrom over the entire plant. The peduncles are from eight to eighteen inches long, slender and limber, and well proportioned to the number of flowers so that they support the flowers semi-pendantly.

The color of the flowers is pure white, comparable to Maerz 8.; Paul Plate No. l-A-l through out the entire blooming period. In all stages of blooming, the flowers have a glossy appearance or sheen, with golden centers, comparable to Maerz & Paul Plate No. l1-L-9.

Each flower has from twenty-five to thirty shell-shaped petals with slightly irregular cristatc edges, and are irregularly imbricated.

The variety is characteristically a persistent grower and a profuse and abundant bloomer, rarely recurrent, the flowers being abundant throughout the blooming period which begins in June (northern Ohio) and lasts five to six weeks. During the blooming period the flowers are substantially consistent in quantity and quality.

The blooms and plant are excellent for cutting and the flowers have good lasting qualities both as to physical condition and color, whether out or uncut.

The plant is distinguished principally, by a most exceptional prolificacy of bloom, which so completely covers the growth that the plant resembles a single large and compact bouquetof glossy white blossoms. Additionally, it is distinguished by the purity and permanence of the white petals of the flowers, the very pronounced strong briar scent, and the hardiness of the plant and its resistance to black-spot and mildew.

The following tabulation is a detailed description' of the new variety Polaris.
