Abstract: A new and distinct cultivar of Diascia plant named `Diastrapin,` particularly distinguished by its light coral flowers and trailing habit.
Claim: What is claimed is:

1. A new and distinct cultivar of Diascia plant named `Diastrapin,` as substantially illustrated and described herein.
Description: Latin name of the genus and species of the plant claimed: Diascia barberae.

Varietal denomation: `Diastrapin`.


The present invention comprises a new distinct cultivar of Diascia, botanically known as Diascia barberae.

The new cultivar is propagated from cuttings resulting from the cross of `A0075-1` and `A0064-1`. `A0075-1` is a pink flowering Diascia. `A0075-1` is not commercially available and is not known by any synonyms. `A0064-1` is a coral floweringDiascia. `A0064-1` is not commercially available and is not known by any synonyms. Both `A0075-1` and `A0064-1` have not been patented.

As a result of this cross the present cultivar was created in 2001 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three-year period. It has been found toretain its distinctive characteristics through successive propagations. The new variety is stable and reproduces true to type in successive generations of asexual reproduction.

This new Diascia plant is an annual in most climatical zones in the US, only in zones 8, 9 and 10 it is a perennial plant.


This new Diascia plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.


The following detailed descriptions set forth the distinctive characteristics of this new Diascia. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant historywas taken on 10 week old plants, cultured in 10.5 cm containers, and blossomed under natural light in a greenhouse.

Color readings were taken in the greenhouse under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
