Abstract

A new Diascia plant particularly distinguished by medium-sized rose pink flowers with reddish markings, medium-green foliage with narrow leaves, and a medium-sized semi-upright, tight, and well-branched plant habit is disclosed.

Description

Genus and species: Diascia barberae.
Variety denomination: ‘Dala Rossa’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of Diascia, botanically known as Diascia barberae, and hereinafter referred to by the cultivar name ‘Dala Rossa’. The new cultivar originated from a hybridization made in 2002 in Andijk, The Netherlands. The female parent is a proprietary Diascia plant designated ‘DSY-3-1’ (unpatented), having pink flowers and the male parent is a proprietary Diascia plant designated ‘DSY-18-1’ (unpatented), having a deep rose flower color. The seeds produced by the hybridization were sown in November 2002, and the resulting seedlings were selected in February 2003. A single plant selection was chosen for further evaluation and for asexual propagation in the summer of 2003.
The new cultivar was created in 2002 in Andijk, The Netherlands and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture micropropagation in Andijk, The Netherlands over a two-year period. The plant has also been trialed at Gilroy, Calif., and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Plant Breeder's Rights for this cultivar were applied for in Europe on Jan. 24, 2005 and in Canada on Mar. 31, 2005.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Gilroy, Calif. and Andijk, The Netherlands.
    • 1. Medium-sized rose-pink flowers with reddish markings on the inner part of the corolla;
    • 2. Medium-green foliage with relatively narrow leaves;
    • 3. A medium-sized, semi-upright plant habit; and
    • 4. A tight and well-branched plant habit.
DESCRIPTION OF PHOTOGRAPH
This new Diascia plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of three 6-month-old plants grown in a greenhouse with natural light in spring trial setting.
The accompanying photograph shows blooms, buds, mature foliage, and plant habit; the inset shows mature inflorescences and buds.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Dala Rossa’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on seven-month-old plants grown, 3 plants each, in 35-cm-diameter baskets (capable of holding 5-liters of soil) in an outdoor trial field under poly-cover rain protection. Color readings were taken under natural light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).
