Miniature rose plant named `MOR Brown`

Abstract

This invention relates to a new and distinct cultivar of miniature rose, primarily identified by the apricot color of its petals and double flowers .

Description

The present invention relates to a new and distinct culvitar of hardy, dwarf, bush type rose plant of the miniature class. The cultivar is primarily charcterized as to novelty by its apricot color and double flowers.

The cultivar is further characterized by:

An abundance of blooms, with flowers usually borne singly to the stem.

Slight Fragrance.

A plant of vigorous, rounded to upright growth shape, with semi-glossy to matte foliage with pointed leaflets; the buds and flowers being similar in form to `MORyou` (`Just For You`, miniature rose; U.S. Plant Pat. No. 8,200) but differing in color, being apricot instead of pink.

A plant which grows and blooms satisfactorily both in greenhouse and outdoors; with repeat bloom, is good for growing in pots, and provides excellent garden decoration as well as cut flowers.

The present cultivar of miniature rose was originated by me at my nursery, located at Visalia, Calif., under conditions, of careful control and observation, as a result of a cross between `MORseqold` (`Sequoia Gold`, miniature rose; U.S. Plant Pat. No. 6,617) as the seed parent and `Golden Angel` (U.S. Plant Pat. No. 4,028) as the pollen parent.

Subsequent to my origination of the cultivar I successfully asexually reproduced this new cultivar at my nursery, located as aforementioned, by budding as well as by cuttings; the reproductions have run true in all respects.

The photograph illustrates the cultivar including the foliage, buds and flowers (stamens not shown).

Plant part coloration illustrated is as true as reasonably possible to attain in photographic illustrations of this type.

Referring now specifically to the new and distinct cultivar of miniature rose plant, the following is a detailed description thereof in outline; all major color plant identification by reference to the R.H.S. Colour Chart (Royal Horticultural Society) except where common terms of color definition are employed.

Outside petal: Outside surface-- orange (apricot) near Orange Group 26C. Inside surface-- near Orange Group 26C blending into yellow at petal base. Intermediate petal: Outside surface similar to outside petal; Inside surface similar to outside petal. Inner petal: Outside surface similar to intermediate petal. Inside surface similar to intermediate petal. General color effect: newly opened flowers-- apricot. 3 days open--color similar to newly opened flower, but lighter and less bright. Flower(petal) color becomes progressively lighter as the flowers age.

Reproductive organs:

Stamens.--Moderately abundant, arranged regularly about the pistol.
