plant named ‘Cunapibi’

Abstract

A new Cuphea plant named ‘Cunapibi’ particularly distinguished by the very small, light purple and red-purple bi-colored flowers, medium green foliage, vigorous, compact but decumbent and well-branched and very floriferous plant habit.

Description

Latin name of the genus and species of the plant claimed: Cuphea ramosissima.

Varietal denomination: ‘Cunapibi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Cuphea, botanically known as Cuphea ramosissima, and hereinafter referred to by the variety name ‘Cunapibi’.

‘Cunapibi’ is a product of a planned breeding program. The new cultivar ‘Cunapibi’ has very small, light purple and red-purple bi-colored flowers, medium green foliage, vigorous, compact but decumbent and well-branched and very floriferous plant habit.

‘Cunapibi’ is a F5 generation and originates from a self-ing hybridization made in a controlled breeding program in Enkhuizen, Netherlands. The female parent was an unpatented, seedling from F4 seed received from a seed bank in Ohio, USA, identified as ‘E0081-2’ with red-purple bicolored flowers and larger, lighter green foliage, and is less floriferous.

The pollination was made in August 2005. The resultant seed was sown in March 2006.

‘Cunapibi’ was selected as one flowering plant within the progeny of the stated cross in a controlled environment in May 2006 in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘Cunapibi’ was accomplished when vegetative cuttings were taken from the initial selection in May 2006 in a controlled environment in Enkhuizen, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2006 in Enkhuizen, Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Cunapibi’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Cunapibi’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has been applied for in CPVO on Nov. 24, 2009 (No. 2009/2471). ‘Cunapibi’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Cuphea as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Cunapibi’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety, and a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in late August 2010 on plants that were growing in 1 gallon pots in a greenhouse in Gilroy, Calif. These plants were approximately 2 months of age.
