Geranium plant named ‘Solstice Purple’

Abstract

A new and distinct cultivar of Geranium plant named ‘Solstice Purple’, characterized by its upright, outwardly spreading and mounded growth habit; freely branching habit; dense and full plant habit; freely flowering habit; red purple and dark purple-colored flowers; and no requirement for vernalization.

Description

Botanical classification/cultivar designation: Pelargonium grandiflorum cultivar Solstice Purple.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, commercially known as Regal Geranium, botanically known as Pelargonium grandiflorum, and hereinafter referred to by the name ‘Solstice Purple’.

The new Regal Geranium is a product of a planned breeding program conducted by the Inventor in Foxley, Dereham, Norfolk, United Kingdom. The objective of the breeding program is to develop new Regal Geranium cultivars with compact growth habit, early flowering habit, numerous small flowers, and interesting flower and foliage colors that do not require vernalization for flowering.

The new Regal Geranium originated from a cross-pollination made by the Inventor in June, 2001 of a proprietary Pelargonium grandiflorum selection identified as code number RPOLB4, not patented, as the female, or seed, parent with a proprietary Pelargonium grandiflorum selection identified as code number RPFTJ24, not patented, as the male, or pollen, parent. The cultivar Solstice Purple was discovered and selected by the Inventor as a flowering plant from within the progeny from this cross-pollination in a controlled environment in Foxley, Dereham, Norfolk, United Kingdom.

Asexual reproduction of the new cultivar by terminal cuttings at Foxley, Dereham, Norfolk, United Kingdom, since June, 2002 has shown that the unique features of this new Regal Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Solstice Purple’. These characteristics in combination distinguish ‘Solstice Purple’ as a new and distinct Regal Geranium cultivar:

• • 1. Upright, outwardly spreading and mounded growth habit.
  • 2. Freely branching habit; dense and full plant habit.
  • 3. Freely flowering habit.
  • 4. Red purple and dark purple-colored flowers.
  • 5. No requirement for vernalization.

Plants of the new Regal Geranium differ from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Regal Geranium are more uniform than plants of the female parent selection.
  • 2. Plants of the new Regal Geranium flower earlier than plants of the female parent selection.
  • 3. Plants of the new Regal Geranium and the female parent selection differ in flower color as plants of the female parent selection have purple-colored flowers.

Plants of the new Regal Geranium differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Regal Geranium are more uniform than plants of the male parent selection.
  • 2. Plants of the new Regal Geranium are more compact than plants of the male parent selection.
  • 3. Plants of the new Geranium are more freely branching than plants of the male parent selection.

The new Regal Geranium can be compared to the cultivar, Burghi, not patented. However, in side-by-side comparisons conducted in Foxley, Norfolk, United Kingdom, plants of the new Regal Geranium differed from plants of the cultivar Burghi in the following characteristics:

• • 1. Plants of the new Regal Geranium were more compact than plants of the cultivar Burghi.
  • 2. Plants of the new Regal Geranium were more freely branching than plants of the cultivar Burghi.
  • 3. Plants of the new Regal Geranium had smaller flowers than plants of the cultivar Burghi.
  • 4. Plants of the new Regal Geranium did not require vernalization for flowering whereas plants of the cultivar Burghi required vernalization for flowering.

DETAILED BOTANICAL DESCRIPTION

The cultivar Solstice Purple has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice in a polycarbonate-covered greenhouse during the winter with day temperatures ranging from 18 to 24° C., night temperatures ranging from 16 to 18° C. and light levels ranging from 4,000 to 8,000 foot-candles. Plants used for the photographs and description were about 16 weeks from planting rooted cuttings and were grown in 11.25-cm containers. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
