Filed Aug. 23, 1974, Ser. No. 500,195

Int. Cl. A01h 5/00 US. Cl. Plt.7 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 buds and flowers of deep pink color with reverse (back side) of petals of lighter intensity.

The variety is further characterized by:

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

Little or no fragrance.

A plant which is vigorous, of rounded spreading shape and with semi-glossy, moderately small foliage with pointed leaflets; the flowers and foliage being similar in size to the variety Janna (United States Plant Pat. No. 3,245). The plant, which has a normal height of 14 to 16 inches can easily be maintained at 12 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, Calif, under conditions of careful control and observation, as a cross between Little Darling (floribunda-Plant Pat. No. 1,581, expired) as the seed parent and an unnamed variety [(Rosa Wichuraina Floradora) X (Oakington Ruby Floradora)] all unpatented kinds, 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 color photograph illustrates the variety, including foliage, buds and flowers.
