Rose plant named Minwco

Abstract

This invention relates to a new and distinct variety of miniature rose plant primarily identified by the light pink color and by the long pointed buds of exhibition 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 glowing light pink color and by the long pointed buds of exhibition form.

The variety is further characterized by:

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

Some fragrance.

A plant which is vigorous, of rounded, upright shape with small semi-glossy to matt foliage with pointed leaflets; the buds and flowers being similar in form and size to Dreamglo (miniature--U.S. Plant Pat. No. 4,579).

The plant, which has a normal height of 12-14 inches (30 cm) 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 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 Black Jack (miniature--U.S. Plant Pat. No. 5,671) 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.
