USPP7772P - Miniature rose plant named `Spomaur` - Google Patents

Abstract

The present invention relates to a new and distinct variety of rose plant of the miniature rose class named `Spomaur`. It is characterized particularly by its clear non-fading crimson red petal coloration, occasional white streaks on the outer two or three petals, high-centered bloom, and reflexing or recurling nature of the petals.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature rose class. Among the novel and distinguishing characteristics which distinguish this new variety (varietal denomination `Spomaur`) from all other varieties of which I am aware are its clear crimson red blooms, occasional white streaks on the outer two or three petals, the flowers being high centered and petals recurling as the flower slowly opens. The blooms are borne singly and also in clusters of five to eight blooms per stem. The flowers are long lasting on the plant and maintain their color well upon aging, even in hot weather. The plant has a vigorous, bushy, much branched, upright growth habit and is easy to propagate.

The color and bud form are generally similar to the pollen parent `Centerpiece` with the main difference being that `Centerpiece` has white tint showing at the base of the petals.

Asexual reproduction by budding and by cuttings of the new variety as performed in Washington County, Oreg., have shown that the foregoing and other distinguishing characteristics of same come true to form and are established and transmitted faithfully through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING (PHOTOGRAPH)

The accompanying photograph shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development. The color depictions set forth therein are as nearly true as it is reasonably possible in a color illustration of this character.

The following is a detailed description of my new variety, with color terminology in accordance with the Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in color description herein refers to plate numbers in the aforementioned color chart. "137B" is plate 137B of the Royal Horticultural Society Colour Chart.
