MINIATURE ROSE PLANT Filed Feb. 19, 1968 WITNESS ZNI ZNTUR W My y KJZPH S MUQQE United States Patent 2,921 MINIATURE ROSE PLANT Ralph S. Moore, 2519 E. Noble Ave., Visalia, Calif. 93277 Filed Feb. 19, 1968, Ser. No. 706,725 Int. Cl. A0111 /02 US. Cl. Plt.8 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 characterizedas to noveltyby yellow buds and flowers which in general color effect are bright lemon yellow.

The variety is further characterized by:

An abundance of bloom, with flowers borne singly or several to stem.

Moderate fragrance.

A plant which is vigorous, of rounded upright shape, and with glossy, small foliage with pointed leaflets; the flowers and foliage being similar to the variety Yellow Doll (United States Plant Patent No. 2,450), but more compact and dwarf in plant habit with buds and flowers a more intense and lasting yellow color. The plant which has a normal average height of about 12" at maturity can be easily maintained at or less by occasional trimming.

A plant which grows and blooms satisfactorily both in greenhouse and outdoors; is a good plant 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 Golden Glow, a climber (United States Plant Patent No. 263, expired), as the seed parent and Magic Wand (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.
