Dahlia plant named `Karma Naomi`

Abstract

A dahlia plant variety producing deep mahogany red flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of Dahlia hybrida, known by the varietal denomination `Karma Naomi`. The female parent of `Karma Naomi` is an undistributed, unpatented variety known as `Stratos` and the male parent is an unnamed, undistributed seedling.

SUMMARY OF THE INVENTION

The new variety is a dahlia plant useful for growing outdoors and under glass which produces attractive deep mahogany red flowers on long stems. 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 Naomi` are firmly fixed and are retained through successive generations of asexual reproduction.

COMPARISON WITH PARENTS

The new variety differs from its parents 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.
