Abstract

The subject of the present disclosure is a new and distinct variety of miniature rose plant characterized by creamy white and coral pink buds and flowers of distinctive form and further indentified by the erect, dwarf, compact plant.

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 creamy white and coral pink buds and flowers which in general effect are similar to Magic Carrousel (U.S. Plant Pat. No. 3,601).

The variety is further characterized by:

An abundance of bloom, with flowers borne one to a stem. No side buds.

Light sweet fragrance.

A plant which is vigorous, of upright growth habit with semi-glossy foliage with pointed leaflets; the buds and flowers being similar in form and size to the pollen parent, Sheri Anne (Miniature -- U.S. Plant Pat. No. 3,826).

The plant, which has a normal height of 12 to 14 inches, can easily be maintained at lesser height by occasional trimming.

A plant which grows and blooms satisfactorily both in a greenhouse or 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 in my home greenhouse, located at Garden Grove, Orange County, Calif., under conditions of careful control and observation, as a cross between Neue Revue (Hybrid Tea, non patented) as the seed parent and Sheri Anne (Miniature -- U.S. Plant Pat. No. 3,826) as the pollen parent.

Subsequent to origination of the variety I successfully asexually reproduced it in my garden, located as foresaid, (also propagated by Pixie Treasures Rose Nursery, 4121 Prospect Ave., Yorba Linda, Orange County, Calif., by budding as well as by cuttings; the reproductions havng 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.
