plant named ‘Green Global’

Abstract

A new and distinct variety of Ligustrum plant having a small leaf size and dwarf growth habit.

Description

Botanical classification: Ligustrum sinensis.

Varietal denomination: ‘Green Global’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Ligustrum plant, botanically known as Ligustrum sinensis, referred to by the varietal name ‘Green Global’. The new variety was discovered in 2006 in Suzuka, Japan as a result of a naturally occurring whole plant mutation of an unnamed and unpatented Ligustrum sinensis variety. The new variety was first asexually reproduced by cuttings in Suzuka, Japan in January of 2008. ‘Green Global’ is similar to its parental varietal in leaf color, but differs in leaf size, density, and internode length. When compared to Ligustrum sinensis variety named ‘Swift Creek’ (unpatented), ‘Green Global’ exhibits smaller leaves and lacks leaf variegation. Further, ‘Green Global’s small leaf size and dwarf growth habit help to distinguish ‘Green Global’ when generally compared to other Ligustrum varieties known to the breeder. ‘Green Global’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

DESCRIPTION OF THE DRAWINGS

Except where otherwise indicated, the accompanying photographic drawings illustrate the new variety at 2 years of age, with the color being as nearly true as is possible with color illustrations of this type:

FIG. 1 shows an entire plant of the new variety;

FIG. 2 shows a close-up view of branches and leaves of the new variety;

FIG. 3 shows a close-up view of branches and leaves of the new variety;

FIG. 4 shows a close-up view of lateral branches of the new variety;

FIG. 5 shows a close-up view of a lateral branch of the new variety; and

FIG. 6 shows an entire plant of the new variety at approximately 3 years from the sticking of a cutting from the mother plant.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety. Plants of the new variety were grown outdoors in 15 cm pots, and the color readings and measurements were taken under artificial light on 2 year old plants in Mie Prefecture, Japan. Color references are primarily to The 2015 R.H.S. Colour Chart of The Royal Horticultural Society of London, Sixth Edition.
