Diascia plant named ‘Dala Reeda’

Abstract

A new Diascia plant particularly distinguished by its medium to large red flowers, deep green foliage, compact and well-branched growth habit, rounded and tight plant habit with upright to narrow spreading branches and early flowering is disclosed.

Description

Genus and species: Diascia barberae.

Variety denomination: ‘Dala Reeda’.

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 Reeda’. The new cultivar originated from a hybridization made in 2003 in Andijk, The Netherlands. The female parent is a proprietary Diascia plant designated ‘DSZ-39-6’ (unpatented), having a deep rose flower color and the male parent is a proprietary Diascia plant designated ‘DSZ-41-3’ (unpatented), having a lilac-rose flower color. The seeds produced by the hybridization were sown in May 2003, and the resulting seedlings were selected in July 2003. A single plant selection was chosen for further evaluation and for asexual propagation in the fall of 2003.

The new cultivar was created in 2003 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. 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 to large red flowers;
  • 2. Deep green foliage;
  • 3. Relatively compact and well-branched growth habit;
  • 4. A rounded and tight plant habit with upright to spreading branches; and
  • 5. Relatively early flowering.

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 a spring trial setting.

The accompanying photograph shows blooms, buds, mature foliage, and plant habit; the inset shows buds and mature inflorescences and buds.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Dala Reeda’. 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 in 35-cm-diameter baskets (capable of holding 5-liters of soil and three plants each) 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). Texture description details were observed under a magnifying glass.
