plant named ‘GloBall’

Abstract

A new cultivar of Pittosporum plant named ‘GloBall’ that is characterized by a a spherical overall shape, a compact habit and variegated leaves that are green with irregular cream colored margins.

Description

Botanical classification: Pittosporum tenuifolium.

Variety denomination: ‘GloBall’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Pittosporum plant botanically known as Pittosporum tenuifolium and hereinafter referred to by the cultivar name ‘GloBall’.

The new cultivar was discovered by the inventor in a cultivated area of Otane, New Zealand in 2008. ‘GloBall’ was discovered as a naturally occurring branch mutation of Pittosporum ‘Tiny Tyler’ (not patented).

Asexual reproduction by cuttings of the new cultivar ‘GloBall’ was first performed in 2008 in Otane, New Zealand. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Pittosporum cultivar ‘GloBall’.

• • 1. Pittosporum ‘GloBall’ exhibits a spherical overall shape.
  • 2. Pittosporum ‘GloBall’ exhibits a compact habit.
  • 3. Pittosporum ‘GloBall’ exhibits variegated leaves that are green with irregular cream colored margins.

The closest comparison cultivars are the parent plant Pittosporum ‘Tiny Tyler’ and Pittosporum ‘Golf Ball’ (U.S. Plant Pat. No. 15,329). The new cultivar ‘GloBall’ is distinguishable from ‘Tiny Tyler’ by the following characteristics:

• • 1. ‘GloBall’ exhibits a spherical overall shape and a compact habit. In comparison, ‘Tiny Tyler’ is more egg shaped and has a larger overall height.
  • 2. ‘GloBall’ exhibits variegated leaves that are green with irregular cream colored margins. In comparison, the leaves of ‘Tiny Tyler’ are lighter green in color.

The new cultivar ‘GloBall’ is distinguishable from ‘Golf Ball’ by the following characteristics:

• • 1. ‘GloBall’ exhibits variegated leaves that are green with irregular cream colored margins. In comparison, the leaves of ‘Golf Ball’ are not variegated and are darker green in color.
  • 2. The leaves of ‘GloBall’ are larger than the leaves of ‘Golf Ball’.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Pittosporum ‘GloBall’. The plant in the photograph shows an overall view of a 12 month old plant. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Pittosporum cultivar named ‘GloBall’. Data was collected in Otane, New Zealand from 12 month old outdoor grown plants in 2.5 liter containers. The time of year was Spring in the Southern Hemisphere and the average temperature range was 10 to 25 degrees Centigrade during the day and 5 to 12 degrees Centigrade at night. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2015 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘GloBall’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
