Rose plant named Jelrocami

Abstract

A new and distinct variety of rose plant of the tea class distinguished by its large, double red flowers which are borne on rigid and very long stems, the flowers when fully blown having a current red coloration on the inner surfaces of the petals and a crimson purple coloration on the outer surface of the petals. The flowers are long lasting as cut flowers and the petals drop off cleanly.

Description

BACKGROUND OF THE NEW PLANT

This new rose plant was originated at Richmond, Ind., as a seedling resulting from my crossing of two carefully chosen rose plant varieties with the object of producing a new, double red tea class flower of an original scarlet red color borne on strong, very long stems, the plant to have a vigorous growth habit well adapted to forcing, especially in the summer. After careful study of the seedlings produced by this crossing, the seedling parent of my new rose variety was selected and propagated by bud grafting through several successive generations at Richmond, Ind., which demonstrated that the novel characteristics of the selected parent were fully retained from generation to generation and appeared to be firmly fixed. Plants of this new rose variety are now being grown at Richmond, Ind., and grown commercially for the European market at Antibes, France.

DESCRIPTION OF THE NEW PLANT

The following is a detailed description of my new rose plant as observed on plants being grown at Antibes, France, the color designations being according to The R.H.S. Colour Chart of The Royal Horticultural Society at London, England.

THE PLANT

Prickles:

Shape.--Upper edge -- Straight slightly fringed, inflexed towards the base. Lower edge -- Concave.

Size.--Large.

Quantity.--Medium.

Color.--On young stems -- Reddish. On mature wood -- Pinkish then Havana.

Foliage:

Quantity.--Abundant.

Form of leaf.--Odd pinnate.

Leaflets.--Number: 3, 5 and 7, more often 5. Shape: Oval with rounded apex and narrower and symmetrical margins, serrated, regular and simple. Texture: Leathery Color: Young Foliage: Upper surface -- BronzeGreen 146A. Outer surface -- Medium Green 148B largely smudged with Reddish Brown. Mature Foliage: Upper surface -- Dark Green 147A. Bottom surface -- Medium Green 147B.

Stipules.--Adnate, pectinate, fairly large and linear.

Petiole.--Inner surface -- Grooved, Reddish Brown on young leaves becoming Medium Green on adult foliage. Outer surface -- Light Green and bearing a few small hooked prickles.

THE BUD

Size: Medium.

Shape: Conical before opening of petals.

Length: 3.5 cm. on average outside the calyx and on opening of sepals.

Color of petals: On opening:

Inner surface.--Vermillion Red.

Outer surface.--Officer Red 45A; more and more flushed Cardinal Red 53A toward the base; more or less smudged blackish on outer petals.

Sepals:

Inner surface.--Tomentous, greenish.

Outer surface.--Light Green more or less smudged reddish, the outer sepals having their edges slightly appendiculated.

Character.--Sepals turn outwardly and downwardly at the start of blowing.

Peduncle:

Length.--12 cm. on average.

Character.--Straight, rigid, slighly smudged reddish brown. The peduncle is slightly glandular and sometimes bears a few small hooked prickles.

THE FLOWER

Size of bloom: Large.

Diameter.--12 cm. on average.

Shape: Parallel sides on start of blowing, then opening in hollow cup chorisis; double.

Petalage:

Number.--30 on average.

Arrangement.--Imbricated.

Form.--Wide fan-shaped with entire margins. The unguis is whitish on both sides.

Texture.--Firm.

Color.--On opening: Inner surface -- Vermillion Red 44A. Outer surface -- Vinous Pink 50A. In course of blowing: Inner surface -- Surface Red 43B in center, very slightly flushed with Light Scarlet Red 43C at edge of petals. Outer surface 13 Crimson Purple 52A in center of petals and Vinous Red 50A at edge of petals. At end of blowing: Inner surface -- Currant Red 47B. Outer surface -- Crimson Purple 52A.

Fragrance: Nil.

Persistence: The petals drop off cleanly.

Resistance to diseases: Very good as observed where grown in France.

Lasting quality: As cut flowers, a relatively long time.

REPRODUCTIVE ORGANS

Stamens:

Number.--120 on average.

Anthers.--Normal, fuchsine.

This new variety of rose plant produces large, elegant flowers, particularly in bud, and when fully blown results in a double flower of scarlet red color in the center, slightly lighter on the edge of the inner surface of the petals and crimson purple on the petals in the center of the bloom with vinous red at the outer surface edges. This plant has a vigorous growth habit and a good aptitude for forcing, especially in the summer, and is not particularly affected by the cryptomatic diseases. Also, all parts of the plants of this variety are likely to serve for reproduction purposes.

Claims

1. A new and distinct rose plant of the hybrid tea class, substantially as herein shown and described, particularly distinguished by its large double red flowers, a vigorous growth habit and a good aptitude for forcing.
