Abstract

A new and distinct rose plant having a strong fragrance and bright pink colored flowers with numerous petals.

Description

Botanical classification: Rosa L.

Varietal denomination: ‘RNF Pink 03WL’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of rose plant known by the varietal name ‘RNF Pink 03WL’. The new variety was discovered in April of 2010 in Gifu, Japan. The new variety is the result of a planned breeding program between an unnamed and unpatented Rosa L. variety (female parent) from the breeder's own collection and an unnamed and unpatented Rosa rugosa variety (male parent) from the breeder's own collection. ‘RNF Pink 03WL’ has a different flower color than its female parent. Additionally, ‘RNF Pink 03WL’ exhibits a fragrance like its male parent, but differs from its male parent in its actual fragrance. When ‘RNF Pink 03WL’ is compared to Rosa L. ‘Ever172’ (currently unpatented in the U.S., Japanese Patent No. 20890), the varieties are similar in flower color, not having eyes on their flowers, and in that they exhibit double flowers. However, when compared to ‘Ever172’, ‘RNF Pink 03WL’ has a larger flower size, different number of petals, and exhibits a fragrance. When generally compared to other rose varieties known to the breeder, the new variety differs in its strong fragrance, its type of fragrance, and in flower color. ‘RNF Pink 03WL’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings taken from 3-4 years of age illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows a close-up view of a flower of the new variety;

FIG. 2 shows a view of an entire plant of the new variety;

FIG. 3 shows a view of multiple plants of the new variety; and

FIG. 4 shows the leaves of the new variety.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions first performed via stem cuttings in May of 2011 carried out in Gifu, Japan. Plants of the new variety were grown in a greenhouse under natural light in 15 cm pots with peat moss substrate and with the assistance of heaters in the winter. The color readings and measurements were taken indoors in a greenhouse under natural light on one year old plants grown in containers. Color references are primarily to The 2015 R.H.S. Colour Chart of The Royal Horticultural Society of London, Sixth Edition.
