Gardenia plant named ‘WAH-SG’

Abstract

A new and distinct variety of Gardenia plant, referred to by its cultivar name, ‘WAH-SG’, is provided which forms single, small sized, fragrant, white colored inflorescences. Attractive, glossy, dark green colored foliage is formed, which contrasts beautifully with the blossoms. The vegetation is moderately vigorous and the growth habit is tight, compact, and rounded. The new variety is well suited for proving attractive ornamentation in the landscape.

Description

Botanical/commercial classification:

Latin name—Gardenia jasminoides.

Common name—Gardenia Plant.

Varietal denomination—‘WAH-SG’.

SUMMARY OF THE INVENTION

The new variety of Gardenia jasminoides Gardenia plant was created in a controlled breeding program during the spring of 2006 at Seneca, S.C., U.S.A., by open pollination in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) was the ‘Daisy’ variety (non-patented). The male parent (i.e., the pollen parent) is unknown.

The parentage of the new variety can be summarized as follows:
‘Daisy’ x unknown

The new cultivar was discovered and selected as a single flowering plant within the progeny of the above-stated open-pollination during the summer of 2008 in a controlled environment at Seneca, S.C. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of Gardenia plant of the present invention possesses the following combination of characteristics:

• • (a) forms attractive, fragrant, small-sized single, white-colored inflorescences,
  • (b) exhibits glossy, dark green colored foliage; and
  • (c) provides moderately vigorous vegetation, with tight, compact, and rounded growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the ‘Daisy’ variety (i.e., the seed parent) displays upright to mounded growth habit, whereas the new variety exhibits tight, compact, and rounded growth habit. Moreover, the new variety can be readily distinguished from other similar non-parental varieties. For example, the ‘Kleim's Hardy’ variety (not patented) displays larger flower size, provides a less compact growth habit, and exhibits larger leaves that are spaced farther apart compared to the new variety.

The new variety has been found to undergo asexual propagation at Seneca, S.C., Hickory, N.C., and El Campo, Tex. by softwood cuttings since the summer of 2010. Asexual propagation by softwood cuttings in Seneca, S.C., Hickory, N.C., and El Campo, Tex. has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

The new variety has been named ‘WAH-SG’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs shows as nearly true as it is reasonably possible to make the same, in color illustrations of this character, typical specimens of the new variety. The Gardenia plants of the new variety were approximately one year of age and were observed while growing outdoors at Cochranville, Pa., U.S.A. in 3-gallon containers.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart, 2015 edition), London, England.
