Abstract

A new Diascia plant particularly distinguished by its large apricot flower, early flowering, and a semi-erect habit that becomes spreading as plant develops.

Description

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED
Diascia barbarae.
VARIETY DENOMINATION
‘Diastina’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new distinct cultivar of Diascia, botanically known as Diascia barbarae. The new cultivar is propagated from cuttings resulting from the cross of ‘A 75-1’ and ‘A 64-1’. ‘A 75-1’ is a pink flowering Diascia having a spreading habit and very large flowers. ‘A 75-1’ is not commercially available and is not known by any synonyms. ‘A 64-1’ is a coral flowering Diascia having a semi-errect habit and intermediate flowersize. ‘A 64-1’ is not commercially available and is not known by any synonyms. Neither ‘A 75-1’ or ‘A 64-1’ has been patented. As a result of this cross the present cultivar was created in 1998 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 to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed.
This new Diascia plant is an annual in most climatical zones in the US. Only in zones 7, 8, 9 and 10 it is a perennial plant.
DESCRIPTION OF THE DRAWING
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 conventioal photographic procedures.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of this new Diascia. The data which defines these characteristics were collected from asexual reproduction carrier out in Enkhizen, Netherlands. The plant history was taken on 10 weeks old plants, blossomed under natural light in a greenhouse. Color readings were taken in the greenhouse under ambient high. Color references are primarily to The R.H.S. Color Chart of The Royal Horticultural Society of London.
