USPP31381P2 - Ixora plant named ‘Vista6’ - Google Patents

Abstract

A new and distinct cultivar of Ixora plant named ‘Vista6’ is disclosed, characterized by white flowers and large, dark green foliage. Plants are more vigorous than typical for white flowering Ixora. The new variety is a Ixora, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Ixora taiwanensis.

Variety denomination: ‘Vista6’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as naturally occurring whole plant mutation of the unpatented variety Ixora taiwanensis ‘Hawaiian Pink’, unpatented. The inventor discovered the variety in a commercial planting of the parent variety in Juana Diaz, Puerto Rico in February of 2016.

After identifying the interesting flower color mutation, the inventor observed the single plant mutation for several months. First propagation was performed by terminal vegetative cuttings at a commercial greenhouse during March of 2016, in Juana Diaz, Puerto Rico. Access to all plants was restricted, as plants were kept in a facility belonging to the inventor and not open to the public. Date of first sale was Jan. 31, 2018. This sale was made directly by the inventor or one who obtained the claimed invention directly or indirectly from the inventor. This sale and all public disclosures made before the filing of this application fall within the exception allowed under 102(b)(1).

Through subsequent propagation by vegetative cuttings, 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 ‘Vista6’ 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 ‘Vista6’. These characteristics in combination distinguish ‘Vista6’ as a new and distinct Ixora cultivar:

• • 1. White flowers.
  • 2. Vigorous plant.
  • 3. Large foliage.

PARENT COMPARISON

Plants of the new cultivar ‘Vista6’ are similar to the parent, in most horticultural characteristics. The new variety, however, differs in the following:

• • 1. The new variety has white flowers; parent has pink flowers.

COMMERCIAL COMPARISON

Plants of ‘Vista6’ are similar in some horticultural characteristics to the variety Ixora taiwanensis ‘Dwarf White’, unpatented. The new variety, however, differs in the following:

• • 1. The new variety has larger leaves than the comparator.
  • 2. Plants of the new variety are more vigorous than plants of the comparator.

Plants of ‘Vista6’ are similar in most horticultural characteristics to the variety Ixora taiwanensis ‘Pink’, unpatented. The new variety, however, differs in the following:

• • 1. New variety has white flowers; comparator has pink flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a typical plant of ‘Vista6’ grown outdoors at a commercial nursery in Juana Diaz, Puerto Rico. This plant is approximately 6 months old, shown in a five inch pot. 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.
