Pelargonium plant named `PEQZ0031`

Latin name of the genus and species of the plant claimed: Pelargonium interspecific.

Varietal denomination: `PEQZ0031`.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Pelargonium, botanically known as Pelargonium interspecific, and hereinafter referred to by the variety name `PEQZ0031`.

`PEQZ0031` is a product of a planned breeding program. The new cultivar `PEQZ0031` has deep rose inflorescences held above the medium-green foliage, very heat and drought tolerant with continuous color through the most extreme summer heat, and exceptional edema tolerance on a well-branched plant habit.

`PEQZ0031` originates from a hybridization in a controlled breeding program made in September 2011 in a greenhouse in Guatemala. The female parent was an unpatented, proprietary plant of P. interspecific parentage, identified as `10998-2` with burgundy flowers and a more open plant habit when compared to `PEQZ0031`.

The male parent of `PEQZ0031` was a patented, proprietary plant of P. interspecific parentage, identified as Calliope Burgundy `10972-6` also with burgundy flowers and with larger leaves and a larger plant than `PEQZ0031`. The resultant seed was sown in March 2012.

`PEQZ0031` was selected as one flowering plant within the progeny of the stated cross in July 2012 in a greenhouse in Gilroy, Calif.

The first act of asexual reproduction of `PEQZ0031` was accomplished when vegetative cuttings were propagated from the initial selection in the June 2012 in a greenhouse in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in June 2012 in Gilroy, Calif., and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for `PEQZ0031` are firmly fixed and are retained through successive generations of asexual reproduction.

`PEQZ0031` 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 been applied for. `PEQZ0031` 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 `PEQZ0031` directly from the inventor.

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

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of `PEQZ0031` with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1, 3 flowering plants 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 May 2017 under natural light. These plants were approximately 12 weeks old and were grown in a 4 inch container in a greenhouse trial. The photographs were taken in June 2017.

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