New Guinea Impatiens Plant Named ‘Tamar White’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Tamar White’, characterized by its large white-colored flowers; freely flowering habit with flowers positioned above or beyond the foliage; upright, somewhat outwardly spreading, rounded, uniform and compact plant habit; freely branching growth habit; and glossy dark green leaves.

Description

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name Tamar White.

The new Impatiens is a product of a planned breeding program Inventor in Maasland, The Netherlands. The objective of the breeding program is to develop new Impatiens cultivars with uniform plant habit and attractive flower and foliage colors.

The new Impatiens originated from a cross made by the Inventor in 1998 of two Inventor's proprietary Impatiens hawkeri selections, not patented. The cultivar Tamar White was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Maasland, The Netherlands in 1998.

Asexual reproduction of the new cultivar by terminal cuttings taken at Maasland, The Netherlands, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

1. Large white-colored flowers.

2. Freely flowering habit with flowers positioned above or beyond the foliage.

3. Upright, somewhat outwardly spreading, rounded, uniform and compact plant habit.

4. Freely branching growth habit.

5. Glossy dark green leaves.

In side-by-side comparisons conducted by the Inventor in Maasland, The Netherlands, plants of the new Impatiens differ from plants of the cultivar Moorea, disclosed in U.S. Plant Pat. No. 9,147, in the following characteristics:

1. Plants of the new Impatiens have darker green leaves than plants of the cultivar Moorea.

2. Plants of the new Impatiens flower earlier than plants of the cultivar Moorea.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Impatiens. The photograph comprises a top perspective view of a typical flowering plant of ‘Tamar White’ grown in a 12.5-cm container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Tamar White has not been observed under all possible environmental conditions. The phenotype may vary somwehat with variations in environment such as temperature, light intensity, water status and fertility level, without, however, any variance in genotype. The following observations and measurements describe plants grown in Maasland, The Netherlands, during the early autumn, under commercial practice in a glass-covered greenhouse. Plants used in the following description were about 10 to 12 weeks old from planting rooted cuttings and grown in 12.5-cm containers with one plant per container.

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