Description

Latin name of the genus and species: Gardenia augusta.

Variety denomination ‘PARCUP’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program by the inventor. The crossing resulting in the new variety was made in December 2012, at a nursery in Kulnura, Australia. The seed parent is the commercial variety Gardenia ‘Buttons’, U.S. Plant Pat. No. 24,229. The pollen parent is the unpatented commercial variety Gardenia ‘Grandiflora Star’. The inventor discovered this new variety at the same nursery in March 2016.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘PARCUP’ by semi-hardwood vegetative cuttings during 2016 at the same commercial nursery in Kulnura, Australia. The inventor continued confidential, controlled testing and propagation, assessing stability of the unique characteristics of this variety. Multiple generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘PARCUP’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PARCUP’ These characteristics in combination distinguish ‘PARCUP’ as a new and distinct Gardenia cultivar:

  • 1. Very compact plant habit.
  • 2. Deep green foliage.
  • 3. Single flowers.

COMPARISON TO PARENT VARIETY

‘PARCUP’ is similar in most horticultural characteristics to the seed parent variety Gardenia ‘Buttons’, U.S. Plant Pat. No. 24,229. Plants of the new cultivar ‘PARCUP’ however, differ in the following:

  • 1. The new variety produces a single flower, the seed parent variety produces a semi-double flower.

‘PARCUP’ is similar in most horticultural characteristics to the pollen parent variety Gardenia ‘Grandiflora Star’, unpatented. Plants of the new cultivar ‘PARCUP’ however, differ in the following:

  • 1. New cultivar's leaf apex is obtuse; the pollen parent's apex is acute.
  • 2. New variety's leaf undulation is medium to strong; parent's is weak.

COMMERCIAL COMPARISON

‘PARCUP’ can be compared to the commercial variety Gardenia hybrida ‘LEETHREE’, U.S. Plant Pat. No. 27,599. Plants of the new cultivar ‘PARCUP’ are similar to plants of ‘LEETHREE’ in most horticultural characteristics, however, plants of the new cultivar ‘PARCUP’ differ in the following:

  • 1. Plants of ‘LEETHREE’ are smaller and more compact than plants of ‘PARCUP’.
  • 2. Foliage of the new variety is obovate, with an obtuse apex, foliage of this comparator is elliptic, with an acute apex.
  • 3. Flowers of the new variety are flatter, having a shorter tube length of 1 to 2 cm, compared to the longer 3.5 cm tube length of this comparator.

‘PARCUP’ is similar in most horticultural characteristics to the commercial variety Gardenia ‘LEETWO’, U.S. Plant Pat. No. 27,601. Plants of the new cultivar ‘PARCUP’ however, differ in the following:

  • 1. Plants of ‘LEETWO’ are smaller and more compact than plants of ‘PARCUP’.
  • 2. Flowers of the new variety are wider, having a diameter range of 5 to 7 cm, compared to the 4 to 4.5 cm diameter flowers of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a plant of ‘PARCUP’ grown outdoors in Kulnura, Australia.

FIG. 2 shows a close up of a typical flower of the new variety. The plant is approximately 2 years old, and is shown in an approximate 200 mm container.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
