USPP5671P - Miniature rose plant `Minkco` - Google Patents

Abstract

The subject of the present disclosure is a new and distinct variety of miniature rose plant characterized by the dark red color of the buds and flowers.

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 deep red color of buds and flowers which in general color effect are similar to Red Pinocchio, Floribunda (U.S. Plant Patent No. 812, expired).

The variety is further characterized by:

An abundance of bloom, with flowers borne singly (occasionally several) to the stem.

Slight fragrance.

A plant which is vigorous, of upright, bushy shape with semi-glossy (to matt) small foliage with pointed leaflets; the buds and flowers being similar in form and size to Over The Rainbow (miniature--U.S. Plant Pat. No. 3,472).

The plant, which has a normal height of 12-14 inches, 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 my nursery located at Dallas, Tex., under conditions of careful control and observation, as a cross between Tom Brown (floribunda--not patented) as the seed parent and Over The Rainbow (miniature--U.S. Plant Pat. No. 3,472) as the pollen parent.

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

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

Referring now sepcifically 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 Chart, except where common terms of color definition are employed.
