Abstract

A new Pentas plant named ‘PEZZ0015’ particularly distinguished by the large sized inflorescences and flowers, with pink flowers, dark-green foliage, semi-trailing, 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: ‘PEZZ0015’.

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 ‘PEZZ0015’.

‘PEZZ0015’ is a product of a planned breeding program. The new cultivar ‘PEZZ0015’ has large sized inflorescences and flowers, with light pink colored flowers, dark 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.

‘PEZZ0015’ originates from a cross hybridization of two (2) sibling seedlings in a breeding program made in May 2014 in a greenhouse in Gilroy, Calif. The female parent was identified as ‘PTSAA0181-8’ with white flower color.

The male parent was an unpatented plant identified as ‘PTF0414-1’ with darker pink colored flowers. The resultant seed was sown in August 2016 in Gilroy, Calif.

‘PEZZ0015’ was selected as one flowering plant within the progeny of the stated cross in November 2016 in a greenhouse in Gilroy, Calif.

The first act of asexual reproduction of ‘PEZZ0015’ was accomplished when vegetative stem tip cuttings were propagated from the initial selection in January 2017 in a greenhouse in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in June 2019 in Gilroy, Calif., and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘PEZZ0015’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘PEZZ0015’ 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 not yet been applied for. ‘PEZZ0015’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘PEZZ0015’ directly from the inventor.

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 ‘PEZZ0015’ 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 early September 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 17 weeks old growing in a gallon pot in a greenhouse trial. The photographs were taken in June 2019.

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