USPP26713P3 - Pittosporum plant named ‘SEASIDE’ - Google Patents

Abstract

A new and distinct Pittosporum cultivar named ‘SEASIDE’ is disclosed, characterized by typically undulating, oblong leaves and dense growth habit. Branches of the plant arise at an acute angle. The new variety is a Pittosporum, typically produced as an outdoor ornamental plant.

Description

Latin name of the genus and species: Pittosporum tenuifolium.

Variety denomination: ‘SEASIDE’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of a controlled breeding program. The new variety was discovered as a seedling from a group of 6 seeds collected from the parent variety, Pittosporum tenuifolium ‘Golf Ball’, U.S. Plant Pat. No. 15,329. The pollen parent is unknown, several Pittosporum varieties were present in the commercial field. After several season of observation, and confidential testing, ‘Seaside’ was selected as a superior cultivar in May of 2010, by the inventor, Luen Miller at a commercial nursery in Royal Oaks, Calif.

Asexual reproduction of the new cultivar ‘SEASIDE’ was first performed by vegetative cuttings in September of 2011 at a commercial nursery in Royal Oaks, Calif. Access to all plants was restricted, as plants were kept in a location not open to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SEASIDE’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SEASIDE.’ These characteristics in combination distinguish ‘SEASIDE’ as a new and distinct Pittosporum cultivar:

• • 1. Dense growth.
  • 2. Typically undulating leaves.
  • 3. Oblong foliage shape.
  • 4. Acute angle of attachment of lateral branches.

PARENT COMPARISON

Plants of the new cultivar ‘SEASIDE’ are similar to the parent, Pittosporum ‘Golf Ball’ in most horticultural characteristics. ‘SEASIDE’ however, differs in producing longer, narrower foliage, with an undulating aspect not found in foliage of ‘Golf Ball’. Additionally, plants of ‘SEASIDE’ are denser than plants of ‘Golf Ball’. The angle of branches of ‘SEASIDE’ is significantly more acute than the angle of branches of ‘Golf Ball’.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SEASIDE’ can be compared to the commercial variety ‘Elfin’ U.S. Plant Pat. No. 21,822. Plants of the these cultivars are similar in most horticultural characteristics, however, ‘SEASIDE’ differs in producing longer, narrower foliage with an undulating aspect not found in foliage of ‘Elfin’. Additionally, plants of ‘SEASIDE’ are larger and denser than plants of ‘Elfin’. The angle of branches of ‘SEASIDE’ is significantly more acute than the angle of branches of ‘Elfin’.

Plants of the new cultivar ‘SEASIDE’ can be compared to the commercial variety ‘Silver Ball’ U.S. Plant Pat. No. 25,705. Plants of the these cultivars are similar in most horticultural characteristics, however, ‘SEASIDE’ differs in the following:

• • 1. Foliage of ‘Seaside’ is Green, whereas foliage of ‘Silver Ball’ is Grey-Green with an irregular white margin.
  • 2. Foliage of ‘Seaside’ has a strong undulation not found in foliage of ‘Silver Ball’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plants of ‘SEASIDE’ grown in Royal Oaks, Calif. Plants are approximately 2 years old.

FIG. 2 illustrates in full color branches of ‘SEASIDE’ compared with branches of ‘Golf Ball’.

The photographs were 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.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used.
