Geranium plant named ‘Balcolreim’

Abstract

A new and distinct cultivar of geranium plant named ‘Balcolreim’, characterized by its semi-double 1-colored flowers, dark green-colored foliage and vigorous, mounded and cascading growth habit.

Description

Latin name of genus and species of plant claimed: Pelargonium peltatum.

Variety denomination: ‘Balcolreim’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of geranium plant botanically known as Pelargonium peltatum and hereinafter referred to by the cultivar name ‘Balcolreim’.

The new cultivar originated in a controlled breeding program in Santa Paula, Calif., during December 1994. The purpose of the breeding program was the creation of geranium plants with vigorous upright mounded and cascading growth habits, dark green-colored foliage and new and unique flower colors.

The female parent of ‘Balcolreim’ was the cultivar ‘Butterfly’ (not patented). The male parent of ‘Balcolreim’ was the proprietary Pelargonium peltatum selection designated ‘90777-5’ (not patented). The new geranium was discovered and selected by the inventor as a single flowering plant from within the progeny of the above stated cross-pollination during June 1995 at Santa Paula, Calif. and was initially designated ‘16769-2B’.

Asexual reproduction of the new geranium by terminal stem cuttings since 2001 at Arroyo Grande, Calif. and West Chicago, Ill., has demonstrated that the new geranium reproduces true to type, with all characteristics as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new geranium 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, without, however, any variance in genotype.

It was repeatedly found that the cultivar of the present invention:

• • 1. Forms semi-double red-colored flowers,
  • 2. Forms dark green-colored foliage, and
  • 3. Exhibits a vigorous mounded and cascading growth habit.

Plants of the new cultivar differ from plants of the female parent and plants of the male parent ‘90777-5’ primarily in flower color.

Of the many geranium cultivars known to the inventor, the most similar in comparison to ‘Balcolreim’ is ‘Balcolred’, disclosed in U.S. Plant patent application Ser. No. 10/099,261 (abandoned). However, in side-by-side comparisons, plants of ‘Balcolreim’ exhibit larger umbels and smaller leaves than the plants of ‘Balcolred’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings show 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. Colors in the photographs differ slightly from color values cited in the detailed description, which accurately describes the colors of ‘Balcolreim’. The plants were grown for 8 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England 1995 edition, except where color terms of ordinary significance are used. The color values were determined on Aug. 13, 2003 in West Chicago, Ill. The readings were taken between 10:00 and 11:45 a.m. under natural light conditions.

The plants used for the following measurements and descriptions were produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 8 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65°-70° F. (18°-21° C.) during the day and approximately 60°-65° F. (15°-18° C.) during the night. Greenhouse light levels of 4,000 to 6,000 footcandles were maintained during the day. Plants were pinched at three weeks after planting.
