Abstract

An Achimenes plant named Pink Rose.

Description

The present invention comprises a new and distinct cultivar of Achimenes plant, hereinafter referred to by the cultivar name Pink Rose.

Pink Rose is a product of a planned breeding program which had the objective of creating new Achimenes cultivars having superior vigor, good branching habits, suitability for pot plants or hanging baskets, double flowers 2" or more in diameter and of various colors, early-flowering, floriferousness, and a long flowering season. Such traits in combination were not present or needed improvement in previously available commercial cultivars of this type.

Pink Rose was originated from a hybridization made in a controlled breeding program in Greenwood, S.C. in 1984. Both the male and female parent were identified by the breeding number 840942-1, with the female parent being selfed from the male parent.

Pink Rose was discovered and selected as one flowering plant within the progeny of the stated percentage by Linda Saussy Wiles on Aug. 21, 1985, in a controlled greenhouse environment in Greenwood, S.C.

Asexual reproduction of the new cultivar by rhizomes, as performed initially by Linda Saussy Wiles at Greenwood, S.C. has demonstrated that the combination of characteristics as herein disclosed for Pink Rose are firmly fixed through successive generations of asexual reproduction.

Pink Rose has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. The following observations, measurements, and comparisons describe plants grown in Greenwood, S.C. under greenhouse conditions which approximate those generally used in commercial practice.

The following traits have been repeatedly observed and are determined to be basic characteristics of Pink Rose, which in combination distinguish this Achimenes as a new and distinct cultivar:

(1) The flowers are double in form and 1.7" to 2.0" in diameter. There are five (5) full size petals and 5 to 9 or more smaller petals measuring 0.7"×0.7" or more when fully expanded.

(2) The upper surface flower color of the outer petals is an attractive Light Pink with the petals showing Silver White on the reverse or underside. Under stress conditions, double petals may retract somewhat into the throat showing very small area of HCC 601-3 Primrose Yellow, with 5 lines and (not too many) dots of HCC 27 Magenta also being apparent.

(3) Generally, two to three flowers appear at each node. Plants are erect when young, and semi-trailing towards end of growing season.

(4) Rhizomes start growing early, producing plants rapidly. From rhizomes planted in early April, flowering plants were available by mid-June.

(5) Plants continue to flower well into late November.

(6) Highly floriferous flowering habit.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to Pink Rose is Blue Rose, disclosed in U.S. Plant Pat. No. 5,919. Reference is made to attached Chart A which compares certain characteristics of Pink Rose to those same characteristics of Blue Rose.

The accompanying color photographic drawings show typical inflorescence and foliage characteristics of Pink Rose, with the colors being as nearly true as possible with illustrations of this type. Sheet 1 is a perspective view of the plant, and sheet 2 comprises a greatly enlarged photo of a single flower and surrounding foliage.

In the following description, color references are made to the Horticultural Colour Chart (HCC), or to The Royal Horticultural Society Colour Chart (RHS) where indicated. The color values were determined between 2:00 pm. and 3:00 pm. on Sept. 23, 1986 under 2200 foot candles of light intensity at Greenwood, S.C.
