Description

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

Varietal denomination: ‘Imtraoran’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Impatiens, botanically known as Impatiens walleriana.

The new Impatiens is a product of a planned breeding program conducted in Enkhuizen, Netherlands. The new Impatiens cultivar is characterized by a flat and strong outward sreading growing habit, freely branching with branches that tend to grow horizontally, resulting in a big and floriferous plant with very large orange flowers.

The present cultivar originated from a cross-pollination made in 2001, of a proprietary Impatiens selection identified as ‘R3627-1,’ not patented, as the female, or seed parent, with a proprietary Impatiens selection identified as ‘R2299-1,’ not patented, as the male, or pollen parent. ‘Imtraoran’ differs from its parents primarily in flower color.

The present cultivar has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, in Angers, France and in Gilroy, Calif. over a three-year period. The distinctive characteristics of this new Impatiens are stable and reproduced true to type in successive generations of asexual reproduction. It takes 6 to 8 weeks to produce a finished plant, depending on the temperature.

This new Impatiens plant is an annual in most climatical zones in the USA, only in zones 9 and 10 it is a perennial plant.

DESCRIPTION OF THE DRAWING

This new 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 Impatiens. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 25 week old plants, blossomed under natural light in the field.

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