Latest Ball Floraplant, a division of Ball Horticultural Co. Patents:
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 Balcolav.
The new Geranium is a product of a planned breeding program conducted by the Inventor in Arroyo Grande, Calif. The objective of the breeding program was to develop new cultivars with freely-branching and vigorous growth habit, medium or dark green-colored foliage, uniform flowering, and interesting flower and foliage colors.
The new Geranium originated from a cross made by the Inventor of the proprietary Pelargonium peltatum selection BFP-1137 as a male, or pollen parent, with the proprietary Pelargonium peltatum selection BFP-1370 as the female, or seed parent. The cultivar Balcolav was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Arroyo Grande, Calif., in December, 1996.
Asexual reproduction of the new cultivar by terminal cuttings taken at Arroyo Grande, Calif., has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTIONThe following traits have been repeatedly observed and are determined to be the unique characteristics of `Balcolav`. These characteristics in combination distinguish `Balcolav` as a new and distinct cultivar.
1. Numerous lavender-colored double flowers.
2. Upright and spreading growth habit.
3. Basal branching and vigorous.
4. Medium green leaves with dark maroon zonation pattern.
The new Geranium differs from plants of its sibling cultivar, `Balcolburg`, U.S. Plant patent application Ser. No. 09/257,098, primarily in plant habit and flower color.
The new Geranium differs from plants of its sibling cultivar, `Balcolilac`, U.S. Plant patent application Ser. No. 09/257,088, in plant habit, leaf zonation pattern, flower form, flower size and number of petals per flower.
The new Geranium differs from plants of its sibling cultivar, `Balcolink`, U.S. Plant patent application Ser. No. 09/257,099, in plant habit, number of flowers per umbel, flower form, and flower color.
The new Geranium can be compared to the cultivar, Butterfly, not patented. However, in side-by-side comparisons conducted in Arroyo Grande, Calif., plants of the new Geranium differ from plants of the cultivar Butterfly in the following characteristics:
1. Plant habit of the new Geranium is upright and spreading whereas plant habit of the cultivar Butterfly is upright and trailing.
2. Plants of the new Geranium usually have fewer flowers per umbel than plants of the cultivar Butterfly.
3. Flower color of the new Geranium is slightly lighter than flower color of the cultivar Butterfly.
A detailed comparison of plants of the cultivar Balcolav and the cultivar Butterfly, as grown side by side, appears in Chart A at the end of the specification.
BRIEF DESCRIPTION OF THE PHOTOGRAPHThe accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a side perspective view of a typical plant of `Balcolav`. Flower and foliage colors in the photograph may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTIONThe cultivar Balcolav has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in 10-cm pots in Arroyo Grande, Calif., under commercial practice in a glass-covered greenhouse with day temperatures about 20 to 22.degree. C., night temperatures about 18 to 20.degree. C. and light levels generally about 2,500 to 3,000 footcandles.
