Abstract

A new Pentas plant named ‘PEZZ0002’ particularly distinguished by the large sized inflorescences and flowers, with blush white colored flowers, dark yellow-green foliage, upright, sturdy and vigorous growth habit, thick stems and branches on a well-branched plant, tolerates hot summer conditions with continuous summer flowering.

Description

Latin name of the genus and species of the plant claimed: Pentas lanceolata.

Varietal denomination: ‘PEZZ0002’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Pentas, botanically known as Pentas lanceolata, and hereinafter referred to by the variety name ‘PEZZ0002’.

‘PEZZ0002’ is a product of a planned breeding program. The new cultivar ‘PEZZ0002’ has large sized inflorescences and flowers, with blush white colored flowers, dark yellow-green foliage, upright, sturdy and vigorous growth habit, thick stems and branches on a well-branched plant, tolerates hot summer conditions with continuous summer flowering.

‘PEZZ0002’ originates from a cross hybridization of two (2) sibling seedlings in a breeding program made in October 2007, in a greenhouse in Gilroy, Calif. The female parent was identified as ‘PEZZ0001’ (U.S. Plant patent application Ser. No. 13/998,369) with light-purple flower color.

The male parent of ‘PEZZ0002’ as a sibling to the female parent, was an unpatented plant identified as ‘209-3’ with lavender flowers. The resultant seed was sown in May 2008 in Gilroy, Calif.

‘PEZZ0002’ was selected as one flowering plant within the progeny of the stated cross in September 2008 in a greenhouse in Gilroy, Calif.

The first act of asexual reproduction of ‘PEZZ0002’ was accomplished when vegetative cuttings were propagated from the initial selection in September 2008 in a greenhouse in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in September 2008 in Gilroy, Calif., and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘PEZZ0002’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘PEZZ0002’ 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 was applied for in Canada on Nov. 2, 2013, No. 12-7779. ‘PEZZ0002’ 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 Pentas as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘PEZZ0002’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1. a flowering plant of the new variety and in FIG. 2. a close-up of an inflorescence.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Gilroy, Calif. in late August under natural light. These plants were approximately 30 weeks old and were grown in a 1 gallon pot grown first in a greenhouse trial and then outside for about the last 10-12 weeks. The plants shown in the photographs were about 16-18 weeks old growing in a 4.5 inch pot in a greenhouse trial. The photographs were taken in April 2012.

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