Rose plant named Wintonbury Parish

Abstract

A new miniature rose variety having uniquely colored semi-double flowers wherein the bottom two-thirds of the petal is white and the top one-third is light red.

Description

The present invention relates to a new and distinct variety of rose plant of the miniature rose class which was originated by my crossing as seed parent "Poker Chip" (U.S. Plant Pat. No. 4,582) with the pollen of the variety known as "Lady X" (U.S. Plant Pat. No. 2,691). The varietal denomination of this new variety is "Berpar".

This new variety has novel characteristics which distinguish it from its parents and all other varieties of which I am aware. Among the novel characteristics it possesses are its unusual semi-double blooms which are white at the base and center of the petals with the top one-third of the petal colored light red of exhibition form and which are long-lasting in the fully open stage. Asexual reproduction by budding of the new variety as performed in Bloomfield, CT, shows that the foregoing and other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of my new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new variety. The color terminology is in accordance with The Royal Horticultural Society Colour Chart. The terminology used in my color description refers to plate numbers in The Royal Horticultural Society Colour Chart, e.g., "4B" refers to plate 4B.
