Abstract

A new and distinct cultivar of Gardenia jasminoides plant named ‘Double Mint’, characterized by fragrant, double white flowers, abundant flowers in spring with reblooming to fall, lustrous, dark green foliage, compact rounded growth habit, cold hardy to USDA Hardiness Zone 7, and resistance to root rot diseases.

Description

Genus and species of plant claimed: Gardenia jasminoides.
Variety denomination: ‘Double Mint’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Gardenia jasminoides, a member of the Rubiaceae family, hereinafter referred to by its cultivar name ‘Double Mint’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant.
The new Gardenia cultivar originated from an open-pollination of Gardenia jasminoides ‘Chuck Hayes’ (U.S. Plant Pat. No. 8,755) as part of a planned breeding program to develop reblooming, double-flowered Gardenias. The cultivar ‘Double Mint’ originated and was discovered in a cultivated environment in an outdoor nursery in Watkinsville, Ga.
‘Double Mint’ has been asexually reproduced by softwood cuttings in Watkinsville, Ga. since 2008, and the characteristics of the cultivar have been stable and reproduced true-to-type in successive vegetative generations.
SUMMARY OF THE INVENTION
‘Double Mint’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.
The following traits have been observed and represent the characteristics of the new cultivar. In combination these characteristics distinguish ‘Double Mint’ from all other varieties in commerce known to the inventor. 1) Fragrant, double white flowers. 2) Abundant flowers in spring with reblooming to fall. 3) Lustrous, dark green foliage. 4) Compact rounded growth habit. 5) Cold hardy to USDA Hardiness Zone 7. 6) Resistance to root rot diseases. There are no other cultivars of Gardenia jasminoides with this combination of characteristics known to the inventor.
‘Double Mint’ is distinguished from its female parent, ‘Chuck Hayes’, by its growth habit, foliage size, and winter foliage color. ‘Double Mint’ has a smaller, more compact growth habit than ‘Chuck Hayes’. ‘Double Mint’ has smaller foliage than ‘Chuck Hayes’. ‘Double Mint’ has foliage that maintains its dark green color during winter, whereas ‘Chuck Hayes’ has foliage that often turns yellow-green in winter.
‘Double Mint’ can be compared to ‘Crown Jewel’ (U.S. Plant Pat. No. 19,896), but differs in the following characteristics. ‘Double Mint’ has a rounded growth habit, whereas ‘Crown Jewel’ has a spreading growth habit. ‘Double Mint’ has smaller foliage than ‘Crown Jewel’. ‘Double Mint’ reblooms from spring to fall, whereas ‘Crown Jewel’ only flowers in spring. ‘Double Mint’ is more resistant to root rot in production than ‘Crown Jewel’.
‘Double Mint’ can be compared to ‘Leeone’ (U.S. Plant Pat. No. 21,983), but differs in the following characteristics. ‘Double Mint’ has a rounded growth habit, whereas ‘Leeone’ has an upright, globose growth habit. ‘Double Mint’ has smaller foliage than ‘Leeone’. ‘Double Mint’ has smaller flowers than ‘Leeone’. ‘Double Mint’ flowers more abundantly than ‘Leeone’.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying illustrations show characteristics of the new cultivar in photographs as true to color as is reasonably possible to make in illustrations of this nature. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gardenia.
FIG. 1 shows the overall appearance of a plant of ‘Double Mint’ planted in the ground.
FIG. 2 shows the overall appearance of a plant of ‘Double Mint’ in a container.
FIG. 3 shows a close-up view of a flower of ‘Double Mint’.
