Description

Latin name of the genus and species of the plant claimed: Verbena×hybrida.

Varietal denomination: ‘Plufrena’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Verbena, botanically known as Verbena×hybrida, and hereinafter referred to by the variety name ‘Plufrena’.

‘Plufrena’ is a product of a planned breeding program. The new cultivar has bold red-purple colored flowers with lighter centers, medium green foliage, medium sized creeping and trailing plant habit with good branching and is early to flower.

‘Plufrena’ originated from a open pollinated hybridization made in summer of 2004 in a controlled breeding environment in Enkhuizen, Netherlands. The female parent was the unpatented, proprietary plant designated ‘E0723-6’ with purple flowers, fewer flowers and has less seed set.

The male parent of ‘Plufrena’ was an unpatented proprietary plant designated as ‘G1368-1’ with smaller deep rose flowers, with foliage with fewer incisions. The resultant seed was sown in February 2005.

‘Plufrena’ was selected as one flowering plant within the progeny of the stated cross in the August 2005 in a controlled environment in Enkhuizen, Netherlands.

The first act of asexual reproduction of ‘Plufrena’ was accomplished when vegetative cuttings were propagated from the initial selection in August 2005 in a controlled environment in Enkhuizen, Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in August 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Plufrena’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Plufrena’ 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.

Plant Breeder's Right for this cultivar were applied for in Canada on Feb. 9, 2010 (10-6832) and in CPVO on Sep. 29, 2009 (2009/1914). ‘Plufrena’ 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 Verbena as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Plufrena’ 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 aforementioned photographs were taken in April 2010 from plants growing in a greenhouse trial in Gilroy, Calif. USA. These plants were growing in 4 inch pots and were approximately 15-16 weeks of age.

The plant descriptions and measurements were taken in late May 2010 in Enkhuizen, Netherlands on about 12 week old plants that had been planted into 12 cm pots and were grown on benches in a greenhouse at a minimum temperature (heating temperature) of 12° C. From April on, a minimum night temperature of 8° C. was held, while day temperatures were much higher, depending on outdoor temperature.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
