Dahlia plant named `Karma Amanda`

Abstract

A dahlia plant variety producing bicolor flowers comprising a creamy white base and violet apex with strong violet streaking all the way to base, violet streaking becomes gradually lighter towards base.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of dahlia hybrida known by the varietal denomination `Karma Amanda`. The seed parent is an unnamed seedling cross of `Stratos` and `Oriental Dream`, both of which are unpatented, undistributed varieties. The pollen parent is unknown due to open pollination.

SUMMARY OF THE INVENTION

The new variety is a dahlia plant useful for growing outdoors and under glass which produces attractive creamy white and violet bicolor flowers. Among the traits possessed by the new variety which in combination distinguish it from other varieties known to the inventor are its attractive flowers borne on long stems.

Asexual reproduction by cuttings of the new variety in The Netherlands has demonstrated that the combination of characteristics as described herein for `Karma Amanda` are firmly fixed and are retained through successive generations of asexual reproduction.

COMPARISON WITH PARENT

The new variety differs from its parent in flower color.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying color photographic illustration shows a typical bloom and leaves of the new variety in colors as nearly true as possible with an illustration of this type.
