Title: Miniature rose plant named `MORhill`

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 very double flowers, the petals being a blend of pink and yellow. 
     The variety is further characterized by: 
     An abundance of blooms, with flowers usually borne several to the stem in loose clusters or sprays, but also sometimes singly. Sepals: permanent; spear shaped; recurved. 
     Some fragrance. 
     A plant which is vigorous, of rounded to bushy shape with small semi-glossy foliage with pointed leaflets; the buds and flowers being similar in form to Pink Petticoat (miniature -- U.S. Plant Pat. No. 4,636). 
     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 Visalia, Calif., under conditions of careful control and observation, as a cross between Little Darling (U.S. Plant Pat. No. 1,581), as the seed parent and Golden Angel (miniature -- U.S. Plant Pat. No. 4,028) as the pollen parent. 
     Subsequent to origination of the variety I successfully asexually reproduced it at the same 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 the foliage, buds and flowers.
