MINIATURE ROSE PLANT Filed Sept. 13, 1962 United States Patent 2,366 MINIATURE ROSE PLANT Ralph S. Moore, 2519 E. Mineral King, Visalia, Calif. Filed Sept. 13, 1962, Ser. No. 223,567 1 Claim. (Cl. Plt.--8)

This invention is directed to a new and distinct variety of hardy, dwarf, bush type rose plant of the hybrid miniature class.

The variety is of the same parentage as the white flowering Easter Morning (United States Plant Patent No. 2,177), and of general similarity in plant, growth, and bloom, including buds and mature flowers. Also, the flowers are similar to Frosty (United States Plant Patent No. 1,412).

The present variety of miniature rose plant, which blooms from spring to frost, is distintively characterized, as to novelty, by:

Flowers whose petals are of softer texture, and often narrower, than those of Easter Morning.

A plant and flowers which are slightly larger than the average miniature, but which plant can be maintained low and neat by pruning.

A good, much branched, early and abundantly flowering plant which can be propagated from cuttings and grown to marketable size faster and easier than any other of the white flowering miniature roses, including Easter Morning; the variety thus being most satisfactory for economical mass production.

A plant which is especially adaptable for growing as a low hedge or garden border.

The variety was originated by me in my nursery located at Visalia, California, under conditions of careful control and observation, as a cross between Golden Glow (United States Plant Patent No. 263) as the seed parent, and Zee (unpatcnted) as the pollen parent; Zee being a miniature rose variety heretofore originated by me, used only for rose plant breeding, and which has not been introduced to the trade.

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

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

The miniature rose plant and its flowers as herein described may vary in slight detail due to climatic and soil conditions under which the variety may be grown;

the present description being of the variety as grown at Visalia, California.

The following is claimed:

A new and distinct varietyfof much branched, spreading, early and abundantly white flowering, miniature rose plant of hardy, dwarf, bush type, as illustrated and described, characterized by a plant and flowers slightly larger than the average miniature rose, a plant which grows from cuttings to maturity faster and easier than any other of the white flowering miniature roses including Easter Morning, and a plant which blooms from spring to frost; and further charactcrizedin comparison with Easter Morningby general resemblance in plant, growth, and bloom but distinctive in that the petals of the white flowers are of softer texture and often narrower.
