plant named ‘Dala Ablos’

Abstract

A new Diascia plant named ‘Dala Ablos’ particularly distinguished by large blush white flowers with pink markings, deep green foliage, rounded leaves, moderately vigorous growth, and a densely branched, mounding to semi-trailing, medium sized plant habit is disclosed.

Description

Latin name of the genus and species of the plant claimed: Diascia barberae.

Varietal denomination: ‘Dala Ablos’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Diascia, botanically known as Diascia barberae, and hereinafter referred to by the variety name ‘Dala Ablos.’

‘Dala Ablos’ is a product of a planned breeding program. The new cultivar' originated from a hybridization made in June 2005 in a controlled breeding program in Andijk, Netherlands.

The female parent was an unpatented, proprietary Diascia plant designated ‘DSZ-39-8,’ having a different salmon flower color and larger and less deep green leaves than ‘Dala Ablos.’

The male parent of ‘Dala Ablos’ was an unpatented, proprietary Diascia plant designated ‘DSZ-41-3,’ having a deeper, light rose, flower color, larger flowers, and longer stems than ‘Dala Ablos.’

The seeds were sown in October 2005 and ‘Dala Ablos’ was selected as one flowering plant within the progeny of the stated cross in January 2006 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Dala Ablos’ was accomplished when vegetative cuttings were taken from the initial selection in the spring of 2006 in a controlled environment in Andijk, Netherlands.

Horticultural examination of plants grown from cuttings of the plant initiated in the spring of 2006 in Andijk, Netherlands, and in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Dala Ablos’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Dala Ablos’ 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.

A Plant Breeder's Right for this cultivar was applied for in the European Union on Jul. 21, 2008. ‘Dala Ablos’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF DRAWING

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, taken in late May 2008, is of a 25 cm diameter basket holding three 15 week old plants grown in a greenhouse during a spring trial setting. The inset shows a close view of a single flower.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, mainly on Apr. 5, 2008 using 8 week old plants that were growing on benches in a greenhouse. Culture of these plants had started in early February with planting rooted cuttings into 12 cm pots. Additional observations were made during the summer of 2008.

Color chart used: The Royal Horticultural Society Colour Chart (R.H.S.), 2001.

BRIEF SUMMARY OF INVENTION

The following observations, measurements, and comparisons describe plants grown indoors and outdoors in Andijk, Netherlands, and in Hillscheid, Germany. The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Diascia as a new and distinct variety:

• • 1. Large, nearly white flowers with pink markings
  • 2. Deep green foliage, medium sized leaves
  • 3. Good branching characteristics, moderately tight structure
  • 4. Medium sized, bushy, mounded and somewhat trailing plant habit
  • 5. Suitable for container planting and hanging baskets

‘Dala Ablos’ differs from the commercial cultivar ‘Flying Colors Appleblossom’ (U.S. Plant Pat. No. 18,837, ‘Diasupa’) in that ‘Dala Ablos’ has a close overall flower color, but less deep pink markings, and lighter, nearly white spurs, slightly larger flowers, but somewhat smaller plant habit.

‘Dala Ablos’ differs from the commercial variety ‘Darla Light Pink’ (‘Dala Litpink,’ U.S. Plant Pat. No. 17,215) mainly by its flower color; it has roughly same flower and plant size.
