Impatiens plant named Waltz

Abstract

A new cultivar of Impatiens plant named Waltz, characterized by its compact growth habit, medium size white flower, unique flower form, small, shiny green leaves, and purple internodes.

Description

The present invention relates to a new and distinctive cultivar of New Guinea Impatiens plant, botanically known as Impatiens, and known by the cultivar name Waltz. Waltz was developed by me through controlled breeding by crossing a cultivar identified by the breeding number 121-12-A1 as the seed parent with a cultivar designated 158-11-A as the pollen parent.

Asexual reproduction by terminal or stem cuttings taken by applicant as Mishmar Hashiva, Israel has shown that the unique features of this new Impatiens are stabilized and are reproduced true to type in successive propagations.

The following characteristics distinguish the new Impatiens from both its parent varieties and other cultivated Impatiens of this type known and used in the floriculture industry:

1. Compact growth habit.

2. White, medium size flower.

3. The shape of the flowers is different than the shape of flowers of existing cultivars having white flower color. A first pair of petals is overlaid by a second pair of relatively narrow petals which are essentially aligned. The petals of both pairs have a single, large indentation in the outer peripheral surface. A fifth petal extends generally perpendicular to the second pair and occupies the entire area between the adjacent petal edges of the second pair of petals. The fifth petal has only a small indentation in its outer edge.

4. The leaves are shiny and dark green in color, and relatively smaller than existing New Guinea Impatiens cultivar.

5. The branches are green, with internodes purple.

The accompanying colored photographs illustrate the overall appearance of this cultivar, showing the colors as true as it is reasonably possible to obtain in a colored reproduction of this type.

The photograph at the top is a top perspective view showing a substantial area of a typical plant in bloom.

The bottom photograph is an enlarged showing of a single flower, with the unique flower form being readily visible.

The following is a detailed description of my new Impatiens cultivar based on plants produced under commercial practice in Mishmar Hashiva, Israel. The description was made in the winter and in the early spring.

Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.

Parentage: 121-12-A.times.158-11-A.

C. Rooting habit.--Good.

Plant description:

A. Form.--Compact, mounded plant.

B. Habit of growth.--Vigorous compact growth, with good branching.

C. Foliage description.--Narrow and small leaves. (1) Size: 8 cm in length and 2.5 cm in width. (2) Shape: Generally oval. (3) Texture: Shiny. (4) Margin: Finely serrated. (5) Color: Young foliage top side, between 137A and 139A; under side 137C. Mature foliage top side, between 137A and 139A; under side 137C. (6) Venation: Light green.

Flowering description:

A. Flowering habits.--Very floriferous, requiring 5 days from bud to flower.
