Abstract

A new and distinct cultivar of Geranium plant named ‘Guinost’, characterized by its compact and upright plant habit; slightly zoned and small leaves; numerous long-lasting dark hot pink-colored semi-double to double flowers; basal branching; high yield of cuttings; early flowering; continuous flowering throughout the summer; and foliage tolerant to rain, wind and stress conditions.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium peltatum, and herinafter referred to by the cultivar name Guinost.
The new Geranium is a product of a planned breeding program conducted by the Inventors in St. Malo, France. The objective of the breeding program was to develop new early-flowering cultivars with interesting and unique flower colors.
The new Geranium orignated from a cross made by the Inventors of the proprietary Pelargonium peltatum selection code number 85 as the male, or pollen parent, with the Pelargonium peltatum cultivar Pico, not patented, as the female, or seed, parent in 1989. The cultivar Guinost was discovered and selected by the Inventors as a flowering plant within the progeny of the stated cross in a controlled environment in St. Malo, France, in 1989.
Asexual reproduction of the new cultivar by terminal cuttings taken at St. Malo, France, 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 INVENTION
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Guinost’. These characteristics in combination distinguish ‘Guinost’ as a new and distinct cultivar:
1. Compact and upright plant habit.
2. Slightly zoned and small leaves.
3. Numerous long-lasting dark hot pink-colored semi-double to double flowers.
4. Basal branching; high yield of cuttings.
5. Early flowering; flowering continuous throughout the summer.
6. Foliage tolerant to rain, wind and stress conditions.
The new Geranium can be compared to the female parent, the cultivar Pico. However, in side-by-side comparisons conducted in St. Malo, France, plants of the new Geranium differ from plants of the cultivar Pico in the following characteristics:
1. Plants of the new Geranium are more compact than plants of the cultivar Pico.
2. Plants of the new Geranium are less vigorous than plants of the cultivar Pico.
3. Plants of the new Geranium flower earlier than plants of the cultivar Pico.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 on the first sheet comprises a side perspective view of a typical plant of ‘Guinost’.
The photograph on the second sheet comprises a close-up view of upper (left) and lower (right) surfaces of typical leaves of ‘Guinost’. Flower and foliage colors in the photographs may appear different from the actual colors due to light reflectance. Both the plants used in the photographs and the plants described in the detailed botanical description were about 7 to 9 weeks in age, and grown under the same environmental conditions as described below.
DETAILED BOTANICAL DESCRIPTION
The cultivar Guinost 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 14-cm pots in St. Malo, France, under commercial practice in a glass-covered greenhouse with day temperatures about 20° C., night temperatures about 18° C. and light levels generally about 450 W/m2. In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
