USPP32472P2 - Gardenia plant named ‘LEESIX’ - Google Patents

Abstract

A new and distinct cultivar of Gardenia plant named ‘LEESIX’ is disclosed, characterized by uniquely profuse flowering. Foliage is narrow and glossy. Flowering will occur on a reblooming cycle Summer and Fall. Flowers are double and very fragrant. Plants are suitable for Southern climates. The new cultivar is a Gardenia, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Gardenia hybrida.

Variety denomination: ‘LEESIX’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program by the inventor. This new variety, hereinafter referred to as ‘LEESIX’, was found as the result of an open pollination conducted during 2007 which included a group of unnamed, unpatented Gardenia hybrida plants as parents. The inventor discovered the unique seedling in Independence, La., at a research nursery during Spring of 2010.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘LEESIX’ by semi-hardwood cuttings during Fall of 2010 at the same nursery in Independence, La. 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 ‘LEESIX’ 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 ‘LEESIX’ These characteristics in combination distinguish ‘LEESIX’ as a new and distinct Gardenia cultivar:

• • 1. Distinctly profuse blooming.
  • 2. Tolerance for environmental stress.
  • 3. Double flowers.
  • 4. Unique narrow leaves.
  • 5. Very fragrant flowers.
  • 6. Repeat blooming in Summer and Fall.
  • 7. Good specimen plant.
  • 8. Good container plant.

COMPARISON TO PARENT VARIETY

The parent varieties are unidentified.

COMMERCIAL COMPARISON

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

• • 1. ‘LEESIX’ has a more open, broad plant habit, compared to the round, compact plant habit of ‘LEETHREE’.
  • 2. ‘LEESIX’ produces double flowers, ‘LEETHREE’ produces single flowers.
  • 3. ‘LEESIX’ flowers more profusely than ‘LEETHREE’.

‘LEESIX’ can be compared to the commercial variety Gardenia hybrida ‘LEETWO’, U.S. Plant Pat. No. 27,601. Plants of the new cultivar ‘LEESIX’ are similar to plants of ‘LEETWO’ in most horticultural characteristics, however, plants of the new cultivar ‘LEESIX’ differ in the following:

• • 1. ‘LEESIX’ has a more open, broad plant habit, compared to the globular, compact plant habit of ‘LEETWO’.
  • 2. ‘LEESIX’ produces double flowers, ‘LEETWO’ produces single flowers.
  • 3. ‘LEESIX’ flowers more profusely than ‘LEETWO’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a plant of ‘LEESIX’ grown outdoors in Alabama.

FIG. 2 shows a close up of typical flowers of the new variety. The plant is approximately 2 years old, and is shown in a three-gallon 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.
