3,246 MINIATURE ROSE PLANT Ralph S. Moore, 2519 E. Noble Ave., Visalia, Calif. 93277 Filed Jan. 11, 1971, Ser. No. 105,745 Int. Cl. A01h 5/00 US. Cl. Plt. 1 Claim 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 bright red buds and flowers which in general color effect are a glowing red similar in color to Scarlet Gem (MiniaturePat. No. 2155), and which tend to become darker red as the flower matures.

The variety is further characterized by:

An abundance of bloom, with flowers borne singly or several to the stem in loose clusters. Sweet fragrance.

A plant which is vigorous, of rounded spreading shape and with semi-glossy, moderately small foliage with pointed leaflets; the buds and flowers being similar in form and size to the variety Tiny Jack (United States Plant Pat. No. 2484). The plant, which has a normal height of 10 to 12 inches can easily be maintained at 8 inches or less 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, California, under conditions of careful control and observation, as a cross between Little Darling (FloribundaPlant Pat. No. 1581, expired) as the seed parent and Magic Wand (Miniature-not patented) as the pollen parent.

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

The figure of the drawing illustrates a spray, including foliage, buds and flowers.
