Rose plant/var. Mormilli

Abstract

This invention relates to a new and distinct variety of miniature rose plant primarily identified by its coral red buds and flowers and hybrid tea form.

Description

The present invention relates to a new and distinct variety of hardy, dwarf, bush type rose plant of the miniature class; the variety being primarily characterized--as to novelty--by the coral red buds and flowers which generally are of exhibition (Hybrid Tea) form.

The variety is further characterized by:

An abundance of bloom, with flowers often borne singly and also several to the stem in loose clusters.

Some fragrance.

A plant which is vigorous, of rounded, upright shape with medium size, semi-glossy to matt foliage with pointed leaflets the buds and flowers being similar in form and size to Starina (miniature--U.S. Plant Pat. No. 2,646--expired).

The plant, which has a normal height of 14-18 inches or more, can easily be maintained at lesser height by occasional trimming. A plant which grows and blooms satisfactorily both in greenhouse and outdoors; is good for growing in pots; and provides excellent garden decoration as well as cut flowers.

The present variety of miniature rose was originated by me at Sequoia Nursery located at Visalia, Calif., under conditions of careful control and observation, as a cross between Little Darling (U.S. Plant Pat. No. 1,581--expired--floribunda) as the seed parent and Galaxy (Variety: MORgal)--miniature--(U.S. Plant Pat. No. 4,580) as the pollen parent.

Subsequent to origination of the variety I successfully asexually reproduced it at Sequoia Nursery, located as aforesaid, by budding as well as by cuttings; the reproductions having run true in all respects.

The color photograph illustrates the variety, including the foliage, buds and flowers.

Referring now specifically to the new and distinct variety of miniature rose plant, the following is a detailed description thereof in outline; all major color plate identifications being by reference to the British Colour Council Horticultural Colour Chart, except where common terms of color definition are employed.

Type: Hardy; dwarf; bushy; upright; seedling; greenhouse; outdoors; cut flowers; garden decoration; potted plant.

Class: Miniature. Variety identification: MORmilli (Commercial synonym: Millie Walters).

Flowers borne: Singly and several together (3 to 5) on slender wirey stems.

Quantity of bloom: Abundant both outside and in greenhouse.

Bud:

Peduncle.--Medium to long; slender but sturdy; erect; medium to light green, sometimes tinted bronze (outdoors); with no prickles and numerous very short hairs.

Before calyx breaks; size.--Small. Form long; pointed with several foliaceous apendages on surface of bud; with foliaceous parts extending beyond the tip of the bud equal to one-half or more of its length.

Color.--Medium green, occasionally tinted with bronze (outdoors).

As calyx breaks, color.--Red, often greenish at base. Opening: opens well in all weather.

Bloom:

Size when fully open.--Small, averaging about 35 mm to 40 mm (11/2" to 15/8").

Petalage.--Double -- Averaging about 45 petals, arranged regularly plus several small petaloids.

Form.--High centered with petals rolled loosely outward and downward. Open flowers may show stamens.

Petals: Fairly thick; satiny on inside and on outside surface.

Shape.--Outside petals, broad lanceolate with small acute tip; intermediate -- broad lanceolate with small acute tip; inside -- lanceolate with acute tip.

Color: Newly opened flower from a plant grown in plastic greenhouse (September 1984), Visalia, Calif.:

Outside petal.--Outside surface -- Near Geranium Laske 20/1 (both lighter and darker) with a slight blueish cast (or veining), becoming yellowish near base. Inside surface -- near Vermilion 18/1 (with orangish tones) becoming whiteish to yellowish at base.

Intermediate petal.--Outside surface similar to outside petal. Inside surface similar to outside petal.

Inner petal.--Outside surface -- Same as intermediate petal; inside surface -- Same as intermediate petal. General color effect; buds and newly opened flowers -- Coral red with darker reverse. NOTE: Color can vary, depending upon weather, time of year, light intensity, etc., -- The orangish "glow" of buds and newly opened flowers may vary giving the flower a slightly different "color effect". Three days open -- Color -- Similar to newly opened flowers, but lighter color. Behavior -- Opens well in all weather. Spent petals drop off. Flower longevity (September 1984) -- Plant in pot 6-8 days or longer. Cut flowers at living room temperature 4-5 days or longer.

Reproductive organs:

Stamens.--Arranged regularly about pistils.

Filaments.--Varying length, medium long, yellow.

Anthers.--Well formed; yellow.

Pollen.--Little or none.

Pistils.--Average number.

Styles.--Varying length -- medium long; yellowish; bunched.

Ovaries.--All enclosed in calyx.

Hips.--None.

Sepals.--Permanent; spear shaped; recurved.

Seed.--None.

Foliage:

Leaves.--Compound of five (sometimes three or seven) leaflets; medium size; leathery; semi-glossy to matt.

Leaflets.--Shape: Broad, nearly oval; apex acute; base rounded. Color: Medium green; new growth -- normal (medium) green (sometimes tinted reddish). Rachis: Medium strength; upper side may have few or no prickles or hairs; grooved; underside may have several thorns (1 to 3) and few or no tiny prickles or hairs. Stipules: Medium to short length; medium width; short to medium length narrow points which turn out usually at about 45 degrees or more.

Growth:

Habit.--Dwarf; bushy; upright; much branched.

Growth.--Free; vigorous; internodes short.

Canes.--Medium; slender; sturdy.

Main stems.--Color: Medium green.

Thorns.--Several, medium to long, usually straight. Prickles --None. Hairs -- None.

Branches.--Color: medium green. Thorns: several; slender; medium to long -- straight. Prickles: None. Hairs -- None.

The miniature rose plant and its flowers as herein described may vary in slight detail due to climatic, soil and cultural conditions under which the variety may be grown; the present description being of the variety as grown at Visalia, Calif.

Claims

1. A new and distinct variety of miniature rose plant of hardy, dwarf, bushy, upright, much branched habit, substantially as illustrated and described, characterized by buds and flowers of exhibition form, essentially coral red in color with orangish highlights giving the opening buds and flowers a fluorescent glow, with reverse of petals being a slightly darker shade of red, and further characterized by a plant of compact well rounded shape, vigorous, with the main stems and shoots being moderately thorny, the said plant being easy to propagate from cuttings or by budding, with an abundance of medium small semi-glossy to matt foliage and an abundance of flowers borne singly or several to the stem in loose clusters.
