Title: Miniature rose plant named Minuco

Description:
The present invention relates to a new and distinct variety of hardy, low growing ground cover type rose plant of the miniature class; the variety being primarily characterized--as to novelty--by (A) the medium red coloration of the flowers which in general color effect are similar to Red Cascade (miniature--U.S. Plant Pat. No. 3,962) and (B) by the spreading ground cover growth habit. 
     The variety is further characterized by: 
     An abundance of bloom, with flowers usually borne in clusters or sprays. 
     Little or no fragrance. 
     A plant which is vigorous, of dense, spreading habit with semi-glossy small foliage, with pointed leaflets; the buds and flowers being similar in form and size to Red Cascade (miniature--U.S. Plant Pat. No. 3,962). 
     The plant, which has a normal height of 8-12 inches and a spread of up to 5 feet, can easily be maintained at lesser spread by occasional trimming. 
     A plant which grows and blooms satisfactorily outdoors; is good for growing in pots, tubs, hanging baskets or as a ground cover; and provides excellent garden decoration. 
     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 seedling of Red Cascade (miniature--U.S. Plant Pat. No. 3,962), the seed parent being Red Cascade with the pollen parent being (supposedly) the same. 
     Subsequent to origination of the variety I successfully reproduced it, at my nursery as aforesaid, by cuttings; the reproductions having run true in all respects. 
    
    
     The color photograph illustrates the variety, including the foliage, bud 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 Color Council Horticultural Color Chart, except where common terms of color definition are employed.
