Impatiens plant named ‘Balpixred’

Abstract

A new and distinct Impatiens plant named ‘Balpixred’, characterized by its small single red flowers, compact growth habit and dark green leaves.

Description

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

Variety denomination: ‘Balpixred’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Impatiens plant, botanically known as Impatiens walleriana and hereinafter referred to by the cultivar name Balpixred.

‘Balpixred’ is a product of a planned breeding program with the objective of developing Impatiens cultivars with small flowers and compact growth habits.

The female or seed parent of ‘Balpixred’, ‘Red Chico’ (not patented), has a more compact growth habit than ‘Balpixred’. The male or pollen parent of ‘Balpixred’, the proprietary Impatiens selection designated SD01033-2 (not patented), has pink and white bicolor flowers. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross during January 2000 in a controlled environment at Elburn, Ill. The new cultivar was designated BFP-562.

Asexual reproduction of the new cultivar has been carried out at Elburn, Ill. and West Chicago, Ill. by terminal tip cuttings and has demonstrated that the unique characteristics of the new cultivar as herein described are firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) exhibits small red flowers;

(b) forms dark green foliage;

(c) exhibits a good basal branching character; and

(d) exhibits a compact growth habit.

The new cultivar of the present invention can be compared to ‘Fify Red’ (U.S. Plant Pat. No. 11,753). However, in side-by-side comparisons, plants of the new cultivar are more vigorous. Lower surface of leaves of ‘Balpixbros’ are solid green whereas those of ‘Fify Red’ are green with blotches of 183D and the flower color of ‘Balpixred’ is slightly lighter than ‘Fify Red’. “Balpixred can also be compared to its sibling cultivar, ‘Balpixbros’. In side-by-side comparisons flowers of ‘Balpixred’ are darker and more red than those of ‘Balpixbros’.”

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balpixred’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Feb. 13, 2002. The readings were taken between 2:00 and 3:00 p.m. under natural daylight conditions.

Plants used for the following descriptions and measurements were grown in 10 cm pots for 12 weeks from rooted cuttings. The plants were produced from cuttings taken from stock plants and grown in a double poly carbonate covered greenhouse under conditions comparable to those used in commercial practice. A soilless growth medium was utilized while temperatures of approximately 68° to 75° F. (20° to 24° C.) during the day and approximately 55° to 65° F. (13° to 18° C.) during the night and light levels of 4,000 to 6,000 footcandles were maintained.
