Azalea named Nancy Marie

Abstract

A new and distinctive variety of azalea plant particularly adapted for greenhouse forcing and distinguished by its basically white flowers variegated by a middle stripe of a coral color about one-third the petal width and extending the length of the petal, the petal colors being very definitely segregated and producing a star-shaped display of color against an all white background. This plant has a vigorous, sturdy and well branched growth habit, with abundant foliage, a profuse production of blooms and capability of being bloomed at any time of the spring season.

Description

BACKGROUND OF THE INVENTION

This new plant originated as a sport of the azalea variety "Variegated Dogwood", U.S. Plant Pat. No. 4,455, and was discovered by me in February 1982 at Sylmar, Calif., among greenhouse grown plants of the parent variety. The very attractive and distinctive appearance of the sport prompted me to reproduce it by original cuttings to observe its reproduction capability and because of material success in that regard, I continued propagation through successive generations and determined that the novel and distinctive characteristics of this new plant held true from generation to generation and appeared to be firmly fixed.

DESCRIPTION OF THE DRAWINGS

My new variety of azalea plant is illustrated by the accompanying photographic drawing, in which the upper view shows a single blossom in close-up detail and the lower view shows clusters of the flowers and foliage as they would appear looking down on a potted plant, the colors shown being as close to those specified as it is reasonably possible to obtain by conventional photographic procedures.

DESCRIPTION OF THE NEW AZALEA VARIETY

The following is a detailed description of my new variety of azalea plant as observed in greenhouse grown plants at West Chicago, Ill., in March of 1983, the color designations being according to The Horticultural Colour Chart (H.C.C.) of The British Colour Council as published by The Royal Horticultural Society of London, England.

This plant is particularly distinguished by its flower, which is star-shaped in color with each petal being consistently one-third coral surrounded by about one-third white on each side. Unlike its parent "Variegated Dogwood", the petal colors of the flowers of this plant are definitely segregated. Otherwise the general characteristics of this plant are like those of its parent.

Claims

1. The new and distinct variety of azalea plant, substantially as herein shown and described, characterized by its basically white flower petals each having a longitudinal midsection of pink coloration which presents a star-like appearance for the fully opened flower.
