Abstract

A new and distinct cultivar of Gardenia augusta plant named ‘PIIGA-I’, characterized by its large, single white flowers that are produced from spring to frost, lustrous, dark green foliage, compact rounded growth habit, and cold hardiness to USDA Hardiness Zone 6b.

Description

Genus and species of plant claimed: Gardenia augusta L.
Variety denomination: ‘PIIGA-I’
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Gardenia augusta, a member of the Rubiaceae family, hereinafter referred to by its cultivar name ‘PIIGA-I’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant.
The cultivar originated from open-pollination of Gardenia augusta ‘MADGA I’ (U.S. Plant Pat. No. 19,988) in Dearing, Ga., and was selected from the progeny by continued evaluation for floral characteristics, growth habit, and cold hardiness.
‘PIIGA-I’ has been asexually reproduced by softwood cuttings in Watkinsville, Ga. since 2005, and the characteristics of the cultivar have been stable and reproduced true-to-type in successive vegetative generations.
SUMMARY OF THE INVENTION
‘PIIGA-I’ 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 ‘PIIGA-I’ from all other varieties in commerce known to the inventor. 1) Large, single white flowers that are produced from spring to frost. 2) Lustrous, dark green foliage. 3) Compact rounded growth habit. 4) Cold hardiness to USDA Hardiness Zone 6b.
‘PIIGA-I’ is distinguished from its female parent ‘MADGA I’ by its vigor, growth habit, flower size, foliage size, fruit production, and cold hardiness. ‘PIIGA-I’ has a more vigorous and larger growth habit than ‘MADGA I’. ‘PIIGA-I’ has larger flowers and foliage than ‘MADGA I’. ‘PIIGA-I’ produces less fruit than ‘MADGA I’. ‘PIIGA-I’ is more cold hardy than ‘MADGA I’ based on field testing in Watkinsville, Ga. and Louisville, Ky. There are no other cultivars of Gardenia augusta with this combination of characteristics known to the inventor.
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 mature plant of ‘PIIGA-I’.
FIG. 2 shows a close-up view of a flower of ‘PIIGA-I’.
FIG. 3 shows a comparison of the growth habit, foliage size, and flower size of ‘PIIGA-I’ (right) to ‘MADGA I’ (left).
 DETAILED DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
