plant named ‘LEEFOUR’

Abstract

A new and distinct Gardenia cultivar named ‘LEEFOUR’ is disclosed, characterized by a upright growth habit and suitability 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: ‘LEEFOUR’.

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 ‘LEEFOUR’, was found as an openly pollinated seedling in a group of Gardenia jasminoides ‘Daisy’ (unpatented) seedling plants being grown in Independence, La. The inventor, Robert Edward Lee, discovered the seedling in Independence, Louisiana, at a research nursery during October of 2000.

After identifying the new variety as a potentially interesting selection, the inventor first organized propagation of ‘LEEFOUR’ by vegetative cuttings during 2004 at the same commercial 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 ‘LEEFOUR’ 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 ‘LEEFOUR’ These characteristics in combination distinguish ‘LEEFOUR’ as a new and distinct Gardenia cultivar:

• • 1. Upright, vigorous growth habit.
  • 2. Tolerance for heat and disease
  • 3. Adaptability to production and use in Southern climates.
  • 4. Excellent flower fragrance.
  • 5. Extremely compact growth
  • 6. Deep green, shiny foliage
  • 7. Good specimen plant
  • 8. Good container plant

COMPARISON TO PARENT VARIETY

‘LEEFOUR’ is similar in most horticultural characteristics to the seed parent variety Gardenia ‘Daisy’ unpatented. Plants of the new cultivar ‘LEEFOUR’ however, are larger and grow faster than plants of ‘Daisy’.

The pollen parent is unknown.

COMMERCIAL COMPARISON

‘LEEFOUR’ can be compared to the commercial variety Gardenia hybrid ‘LEETWO’, U.S. Plant patent application Ser. No. 14/121,171, filed concurrently. Plants of the new cultivar ‘LEEFOUR’ are similar to plants of ‘LEETWO’ in most horticultural characteristics, however, plants of the new cultivar ‘LEEFOUR’ produce larger flowers and overall plant size of ‘LEEFOUR’ is larger and the shape more upright.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

FIG. 2 shows a close up of a typical foliage 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.
