UnitedStates Patent 2,459 MINIATURE RCSE PLANT Ralph S. Moore, 2519 E. Mineral King, Visalia, Calif. Filed June 12, 1963, Ser. No. 287,452 1 Claim. (Ci. Pin-8) This invention relates to a new and distinct variety of hardy, dwarf, bush type of rose plant of the hybrid miniature class.

The present variety of miniature rose plant was originated by me in my nursery located at Visalia, County of Tulare, California, under conditions of careful control and observation, as a seeding which resulted from a cross between Golden Glow, (United States Plant Patent No. 263) as the seed parent and Zee (an unpatented miniature) as the pollen parent.

Subsequent to the origination of the variety and recognition by me of its distinctive features as hereinafter described, I successfully asexually reproduced it in my nursery, located as aforesaid, by budding as well as by cuttings; such asexual reproductions having run true to the original plant in all respects.

In plant habit and shape of flowers, the present variety is generally similar to Easter Morning (United States Plant Patent No. 2,177) but is distinctively characterized as follows:

The variety is the easiest of all yellow flowered miniature roses to propagate and to grow into asaleable plant; this by reason of a very definite ease of rooting from both hard and soft wood cuttings, and a high percentage of survival of newly potted rooted cuttings.

The plant, while vigorous in growth, is quite compact and has an abundance of glossy clean foliage; the plant growing well both outside and in a greenhouse.

The variety is a regular or continuous bearer of double, many petaled flowers having a tea rose fragrance and being clear yellow in color; the buds being well shaped (much like a hybrid tea rose) while the old flowers shed their petals so that the plant is clean and neat in appearance at all times.

The flowers, while remaining a clear yellow, may vary in shade due to light intensity or day length. When the plants are grown in a greenhouse with the use of artificial light to provide in effect an increase in day length, full colored buds and flowers can be produced even during the Winter months.

' In the drawings, FIG. 1 illustrates a spray, including foliage, buds and flowers, and FIG. 2 illustrates a section of a stem, with thorns and a leaf.

Referring now specifically to the new and distinct variety of miniature rose plant, the following is a detailed description thereof in outline; all major color plate identifications being by reference to The British Colour Council Horticultural Colour Chart, except where common terms of color definition are employed.

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 variety of miniature rose plant of hardy, dwarf, bush type, substantially as illustrated and described, having general similarity to-Easter Morning in plant habit and shape of flowers but distinctively characterized by ease of propagation from hard or soft wood cuttings, and a high percentage of survival of newly potted rooted cuttings; by a vigorous, compact, but much branched plant having an abundance of clean glossy foliage, the plants growing well both outdoors and in a greenhouse; by buds which are well shaped and resemble a hybrid tea rose; and by double, many petaled flowers having tea rose fragrance and clear yellow color, which flowers when old shed their petals.
