Miniature rose plant named `Morart`

Abstract

The subject of the present disclosure is a new and distinct variety of climbing miniature rose plant characterized by buds and flowers of good substance and of a color blending orange and yellow.

Description

The present invention relates to a new and distinct variety of hardy, climbing type rose plant of the miniature class; the variety being primarily characterized -- as to novelty -- by orange buds and flowers. The general color effect being orange.

The variety is further characterized by:

An abundance of bloom, with flowers, on mature plant, usually borne several together in loose spray or cluster.

Fruity fragrance.

A plant which is vigorous, of upright, climbing habit with semi-glossy to matt, medium foliage with pointed leaflets; the buds and flowers being similar in form and color to Mary Marshall (Miniature -- U.S. Plant Pat. No. 3,346) but slightly larger.

The plant, which has a normal height of about 6 feet 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 large pots or garden 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 #1-72-1 (Little Darling.times.Yellow Magic), un-named, climbing miniature, as the seed parent and Gold Badge (Var: Meigronuri) Floribunda -- U.S. Plant Pat. No. 4,625 -- as the pollen parent.

Subsequent to origination of the variety I successfully 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 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 Color Chart, except where common terms of color definition are employed.

Three days open -- color similar but lighter (more pinkish). Note: The blending of colors, orange, yellow and pink can vary according to season of year, light intensity, etc. Thus flowers may be slightly lighter or darker than described or illustrated.
