plant named ‘PS-2013-3’

Abstract

A new cultivar of Gardenia named ‘PS-2013-3’ that is characterized by its compact plant habit that is equal in height and width, its dense self-branching plant habit without pruning its large single flowers that bloom in late spring with two full spring cycles under ideal conditions followed by spot blooming through the fall, its glossy dark green foliage, its cold hardiness at least to U.S.D.A. Zone 7 with no winter foliage freezing, and its good resistance to root rot.

Description

Botanical classification: Gardenia jasminoides.

Variety denomination: ‘PS-2013-3’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gardenia jasminoides. The new cultivar will be referred to hereafter by its cultivar name, ‘PS-2013-3’. ‘PS-2013-3’ is a new cultivar of Gardenia grown for use as a landscape shrub.

The new cultivar of Gardenia is a selection from a controlled breeding program conducted by the Inventor in Grand Saline, Tex. The objectives of the breeding program are to create new jasmine cultivars with good cold hardiness, floriferous blooming habits, glossy green foliage, and compact plant habits.

‘PS-2013-3’ originated from open pollination of Gardenia jasminoides ‘Kleim's Hardy’ (not patented) in May of 2011. The male parentage is therefore unknown. ‘PS-2013-3’ was selected as a single unique plant in May of 2013 from amongst the resulting seedlings.

Asexual propagation of the new cultivar was first accomplished by semi-hardwood stem cuttings under the direction of the Inventor in Grand Saline, Tex. in July of 2013. Asexual propagation by semi-hardwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘PS-2013-3’ as a new and unique cultivar of Gardenia.

• • 1. ‘PS-2013-3’ exhibits a compact plant habit that is equal in height and width.
  • 2. ‘PS-2013-3’ exhibits a dense self-branching plant habit without pruning.
  • 3. ‘PS-2013-3’ exhibits large single flowers that bloom in late spring with two full spring cycles under ideal conditions followed by spot blooming through the fall.
  • 4. ‘PS-2013-3’ exhibits glossy dark green foliage.
  • 5. ‘PS-2013-3’ exhibits cold hardiness at least to U.S.D.A. Zone 7 with no winter foliage freezing.
  • 6. ‘PS-2013-3’ exhibits good resistance to root rot.

The female parent of ‘PS-2013-3’ differs from ‘PS-2013-3’ in having wider leaves, in having longer internodes, and in having a less dense, more open plant habit. ‘PS-2013-3’ can be most closely compared to the Gardenia jasminoides cultivars ‘Whispering Pines’ (not patented) and ‘Double Mist’ (U.S. Plant Pat. No. 23,507). ‘Whispering Pines’ is similar to ‘PS-2013-3’ in being resistant to root rot, and in having a bloom season that begins in the spring followed by spot blooming through the fall. ‘Whispering Pines’ differs from ‘PS-2013-3’ in having wider leaves, in having longer internodes, in having double flowers, and in having an open growth habit that is not self-branching. ‘Double Mint’ is similar to ‘PS-2013-3’ in having a long bloom season and in having a plant habit that is equal in height and width. ‘Double Mint’ differs from ‘PS-2013-3’ in having leaves that are shorter in length, in having leaves with more rounded apices, in having double flowers, in having leaves with less pronounced veins, and in having dull green foliage.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Gardenia. The photographs were taken of a 1 year-old plant as grown outdoors in a two-gallon container in Grand Saline, Tex.

The photograph in FIG. 1 provides a side view of the plant habit of ‘PS-2013-3’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘PS-2013-3’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Gardenia.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of 1 year-old plants of the new cultivar as grown outdoors in two-gallon containers in Grand Saline, Tex. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
