plant named ‘Genie-2’

Abstract

A new and distinct variety of Gardenia jasminoides plant named ‘Genie-2’, characterized by its dense, low-profile growth habit, dark green foliage color and abundant fragrant, triple-whorl white flowers is disclosed.

Description

Genus and species: Gardenia jasminoides.

Varietal denomination: ‘Genie-2’.

FIELD OF INVENTION

The present invention relates to a new and distinct variety of the genus Gardenia and a member of the Rubiaceae family. This new Gardenia variety, hereinafter referred to as ‘Genie-2’, was discovered by Allyn Austin Cook in June. 2007. ‘Genie-2’ is characterized by its dense, low-profile growth habit, dark green foliage color and abundant fragrant, triple-whorl white flowers.

BACKGROUND OF THE INVENTION

‘Genie-2’ is derived and selected from gifted, unnamed, without traceable lineage and unpatented seed planted in Alachua County, Fla. Seed was received en masse in 2005. Ten (10) of the seeds were planted. After two (2) years, only one (1) grew with distinction. The exceptional plant subsequently named ‘Genie-2’ grew with a low and mounded profile and was a prolific bloomer.

The value of this new cultivar lies in its low-profile growth habit, compact dark green foliage color and abundant fragrant triple-whorl white flowers. The remarkable attributes of ‘Genie-2’ are its small size, low-profile growth habit, heat tolerance and disease resistance. ‘Genie-2’ is well suited for use in either formal or informal groupings and is quite attractive in mass plantings. ‘Genie-2’ is appropriate, adaptable and quite attractive as a container plant. ‘Genie-2’ is responsive to pruning and training and may be maintained without an excessive amount of care. Its natural propensity to remain small to maturity makes it valuable for landscape uses in any garden size.

Asexual propagation of the new plant by cuttings has been under Dr. Cook's direction and control in Alachua and Hillsborough counties of Florida. The new plant retains its distinctive characteristics and reproduces true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Alachua County, Fla. The combination of these characteristics distinguishes ‘Genie-2’ from all other varieties in commerce known to the inventor. 1. Dense and low-profile in nature. 2. Attractive dark green foliage. 3. The flowers are triple whorl, white, fragrant and profuse. 4. Reaches mature size under normal fertilization and moisture conditions. 5. Hardy to Zone 7. 6. Tolerates part sun to part shade. 7. Heat tolerant. 8. Adaptable to a wide range of soil types. 9. Easily propagated with semi-hardwood cuttings in late spring through summer or through the process known in the industry as “tissue culture.” 10. Requires little pruning but is tolerant if pruning is desired. 11. Relatively pest resistant. 12. Very desirable in containers.

DESCRIPTION OF THE DRAWINGS

This new Gardenia jasminoides cultivar is illustrated by the accompanying photographic prints. The colors shown are as true as is reasonably possible to obtain by conventional photographic procedures. Colors in the photographs may appear different than actual colors due to light reflectance. The colors of the various plant parts are defined with reference to The Royal Horticultural Society Colour Chart. Descriptions of colors in ordinary terms are presented where appropriate for clarity in meaning.

FIG. 1 shows the overall appearance of a plant of ‘Genie-2’ planted in the ground.

FIG. 2 shows a close-up view of a flower of ‘Genie-2’.

FIG. 3 shows the overall appearance of a plant of ‘Genie-2’ in a container.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new variety of Gardenia based on observations made of two-year-old plants grown in one to three gallon containers and in established landscape plantings in Alachua and Hillsborough Counties, Fla., utilizing common gardening techniques. The description includes a comparison with Gardenia jasminoides ‘Leeone’ (U.S. Plant Pat. No. 21,983) and Gardenia jasminoides ‘Daisy’ (unpatented).

Gardenia jasminoides ‘Leeone’ and Gardenia jasminoides ‘Daisy’ are well known in the industry and are comparable to ‘Genie-2’ in that all have green foliage color and white fragrant blooms. However, there are many differences. The growth habit of ‘Genie-2’ is compact, dense and low in profile to a mature height of 1½′ (0.5 m) tall compared to ‘Leeone’ which is upright, globose and much taller—4′ (1.2 m) tall. The flower form of ‘Genie-2 is a triple whorl where ‘Leeone’ is double and ‘Daisy’ is single.
