1 Claim. (Cl. 47-61) My present invention relates to a new type of rose plant known as Grandiflora. This new variety is the first white rose of the Grandiflora class, so far as I know, and is an exceedingly prolific producer of large, fragrant, semi-double, hybrid-tea type white blooms which grow in clusters or candelabra. It is more productive of bloom than any other Grandiflora in my garden.

This new variety is the result of direct breeding effects made by me at my gardens and greenhouse near Medina, and its parentage is Madam Butterfly (unpatented) X New Dawn (PlantPatent No. l) x Crimson Glory (Plant Patent No. 105). The bush is extremely vigorous and averages 3 to 4 feet in height in my nursery. If left unpruned, it would probably grow taller and in mild climates, where the canes are not injured in winter, sometimes grows to a height of 6 to 7 feet. This leads usto believe that it can be grown as a climber in the warmer climates.

This variety has been asexually reproduced by me by the budding method, in my Medina nurseries, and its distingishing characteristics appear to be permanent.

The accompanying illustration shows in approximately true colors, buds and blossoms of my new variety in,

various stages of opening, with portions of the stems and foliage. Also shown are the stamens and pistils of a flower from which the petals have been stripped.

In the following detailed description, color plate references indicate Ridgways Color Standards and Nomenclature. Other use of color names indicates the usual directionary means of the term.

The plant Growth habits: Very vigorous and strong, in this climate producing a bush twice the size of an ordinary hybrid tea, and it has attained a height of seven feet where canes are not injured by winter cold.

Blooming habit: Very prolific, in a single season bearing hundreds of large, fragrant, white blooms in clusters of 3 to 7.

Disease resistance: My new variety has proven more resistant to all forms of blackspot than most varieties. Grown under the same conditions in my gardens, the resistance of my new variety to blackspot is much greater than that of the variety Queen Elizabeth (Plant Patent No. 1,259), which is known as a disease-resistant variety. Among the white rose varieties, two of the well-known ones found much less resistant to blackspot than my new variety are Kaiserin Auguste I {5,,. I. I. 1:.- Form: Tall, vigorous, uprightbushywith a possibility of being grown as a climbing rose in milder climates.

Stems:

Strength.-Main stems are very strong and heavy;

branches progressively smaller as flowers are approached. Stems or canes grow long where winter weather does not kill them back.

Colon-Young stem is Chromium Green (Plate XXXII); old stem Cerro Green (Plate V) partly overlaid with Violet Carmine (Plate XII).

Thorns.-Huge sharp thorns are closely and irregularly spaced. They point slightly downward and are tinged with shades of red ranging from Rose Red to Pomegranate Purple (both Plate XII).

The flower Bud:

Size. Small, approximately inch as calyx breaks.

0pening.Slow and even.

Col0r.Greenish-white (approximately Light Turtle GreenPlate XXXII), with pink flush at tip which is sometimes as dark as Eugenia Red (Plate XIII).

Peduncle.--Strong; approximately 2 inches long.

Calyx.Small; fairly simple; reflexes early; is usual- I 1y pink-tinged inside, particularly near the petals.

Bloom:

B0me.In truss-like or candelabra clusters containing from 3 to 7 flowers.

F0rm.--At first, full and high-centered much like the usual hybrid tea. Later it opens into shallow cupshape with large center of stamens and pistils.

Petalage.Double, with approximately 25 petals as an average.

Color.-Essentially white, but with a definite cream tinge particularly at the base of petals.

Size.Large, measuring 4 to 4 /2 inches when fully open.

Longevity.Lasts well on bush and as cut flower.

Petals:

Texture.-Silky. Size.0uter petals 1 /2 to 2 inches in each dimension. Fragrance.Mild tea fragrance. Persistence.Petals cling until flower dies.

Reproductive organs;

PistilSL-Mziriy; tightly' 'bunched in center of flowers;

MartiusYeH'ow (Plate IV). Stamens.--Loosely bunched around pistils and rising to approximately the same height. Antherslarge; Mikado Orange to Orange Bufi (Plate III). Filaments-graceful curved; Strontian 7 Yellow (:PlateXVI). 1 p 1 i No references cited.
