Botanical classification: Gardenia jasminoides.
Variety denomination: ‘Baildeniaone’.
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, ‘Baildeniaone’. ‘Baildeniaone’ is a new cultivar of Gardenia grown for use as a landscape shrub.
The new cultivar was derived from a controlled breeding program conducted by the Inventors in Watkinsville, Georgia. The goal of the breeding program is to develop new cultivars of cape jasmine with good cold winter tolerance.
‘Baildeniaone’ originated as a seedling that arose from seed planted from open pollination of Gardenia jasminoides ‘Frostproof’ (not patented) in summer of 2008. The male parent is therefore unknown. ‘Baildeniaone’ was selected as a single unique plant in summer of 2009 from the resulting seedlings.
Asexual propagation of the new cultivar was first accomplished by softwood stem cuttings under the direction of the Inventors in Watkinsville, Georgia in summer of 2010. Asexual propagation by softwood 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 ‘Baildeniaone’ as a new and unique cultivar of Gardenia.
- 1. ‘Baildeniaone’ exhibits double flowers with a strong fragrance.
- 2. ‘Baildeniaone’ exhibits a uniform and rounded plant habit without pruning.
- 3. ‘Baildeniaone’ exhibits good cold tolerance, at least to U.S.D.A. Zone 7.
The female parent differs from ‘Baildeniaone’ in having a much smaller plant size. ‘Baildeniaone’ can be most closely compared to the Gardenia jasminoides cultivars ‘Double Mint’ (U.S. Plant Pat. No. 23,507) and ‘PIIGA-II’ (U.S. Plant Pat. No. 27,258). Both are similar to ‘Baildeniaone’ in having fragrant double flowers and rounded plant habits. Both differ from ‘Baildeniaone’ in having smaller plant sizes with lower cold tolerance; sustaining damage at 7° F.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Gardenia. The photograph in FIG. 1 was taken of a 12-year-old plants of the new cultivar as grown in trial garden in Winterville, Georgia. The photographs in FIG. 2 and FIG. 3 were taken of a 1.5-year-old plant as grown outdoors in a 2-gallon container in Yamhill, Oregon.
The photograph in FIG. 1 provides a side view of ‘Baildeniaone’ in bloom.
The photograph in FIG. 2 provides a close-up view of a flower of ‘Baildeniaone’.
The photograph in FIG. 3 provides a close-up view of the foliage of ‘Baildeniaone’.
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 1.5-year-old plants of the new cultivar as grown in 2-gallon containers outdoors in Yamhill, Oregon.

The color determination is in accordance with the 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
