New Guinea Impatiens plant named `Ingborg`

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named `Ingborg` characterized by its large flowers, non fading orange flowers, early flowering, dark green foliage, ball shaped growth habit with excellent basal branching and good vigor.

Description

Latin name of the genus and species of the plant claimed: Impatiens hawkeri.

Varietal denomination: `Ingborg`.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct New Guinea Impatiens plant botanically known as Impatiens hawkeri and referred to by the cultivar name `Ingborg.`

The new cultivar was developed in a controlled breeding program conducted by the inventor in Enkhuizen, Netherlands. The new New Guinea Impatiens cultivar is characterized by an early flowering response, large flowers with attractive coloration, and a good flowering behavior under field conditions.

The new cultivar is propagated from cuttings resulting from the cross in September 1999 of the proprietary New Guinea Impatiens selection identified as `F 54-2` as female parent and the proprietary New Guinea Impatiens selection identified as `F 147-3` as male parent. `F 54-2` is not commercially available and has not been patented. `F 147-3` is not commercially available and has not been patented.

As a result of this cross the present cultivar was selected in September 2000 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Gilroy, Calif., and in Angers, France over a period of several years. The distinctive characteristics of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction. It takes 8 to 10 weeks to produce a finished plant, starting from a rooted plug and planted in a 12 cm pot, depending on the temperature.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Ingborg.` These characteristics in combination distinguish `Ingborg` as a new and distinct New Guinea Impatiens cultivar: 1. Large orange flowers with a stable color 2. Ball shaped growth habit with flowers on top of the foliage 3. Dark green foliage 4. Excellent basal branching 5. Good outdoor vigor

Plants of the new New Guinea Impatiens differ primarily from the plants of the female parent selection in the following characteristics:

Plants of the New Guinea Impatiens have small dark green leaves and are early flowering, whereas the plants of the female parent have large, light green leaves and are later flowering.

Plants of the new New Guinea Impatiens differ primarily from the plants of the male parent selection in the following characteristic:

Plants of the New Guinea Impatiens have orange flowers, whereas the plants of the male have red flowers.

Plants of the new New Guinea Impatiens can be compared to plants of `Fisnics Orange,` disclosed in U.S. Plant Pat. No. 13,225. In side-by-side comparisons conducted by the inventor in Enkhuizen, Netherlands, plants of the new New Guinea Impatiens differed from plants of `Fisnics Orange` in the following characteristics: 1. Plants of the new New Guinea Impatiens have mid green, shiny leaves, whereas the cultivar `Fisnics Orange` has lighter green-colored leaves. 2. Plants of the new New Guinea Impatiens have a ball shaped growth habit with excellent basal branching, whereas the plant of the cultivar `Fisnics Orange` is bush shaped with less branching.

DESCRIPTION OF THE DRAWING

This new New Guinea Impatiens plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new New Guinea Impatiens. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 30 week old plants, blossomed under natural light in the field.

Color readings were taken in the laboratory under ambient light. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.
