USPP21196P3 - Variety of Cuphea plant named ‘Vieburg’ - Google Patents

Abstract

A new and distinct Cuphea llavea plant named ‘Vieburg’ with large, reddish-purple bicolored flowers and an upright growth habit.

Description

Botanical classification: Cuphea llavea.

Varietal denomination: ‘Vieburg’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Cuphea llavea known by the varietal name ‘Vieburg’. The new variety was discovered in 's Gravenzande, The Netherlands on Jul. 7, 2006. The new variety has been asexually reproduced via tip cuttings and the first date of asexual reproduction was Aug. 15, 2006 in 's Gravenzande, The Netherlands. The new variety is the result of a planned breeding program cross between unpatented Cuphea llavea plant Seedling C8 (female parent) and unpatented Cuphea llavea plant Seedling C5-2 (male parent). The purpose of the breeding program was to develop new varieties with bigger flowers and a broad range of color. The new variety exhibits strong growth and an upright habit that are similar to both parents, but does have a bigger flowers and an improved flower color when compared to both parents. ‘Vieburg’ exhibits similar vigor to Cuphea llavea ‘Tiny Winie’ (unpatented and also known as ‘Torpedo’), but has bigger flowers, different flower color and more upright growth than ‘Tiny Winie’. The new variety has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The following characteristics distinguish ‘Vieburg’ from other Cuphea llavea varieties known to the breeder:

• • 1. Large flowers;
  • 2. Bicolored flowers; and
  • 3. Improved upright growth.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:
