Abstract

A new and distinct variety of Geranium plant named `Merisnow`, characterized by its rounded and compact growth habit; moderate growth rate and vigor; fast rooting; dark green foliage color with distinct zonation pattern; numerous peduncles with ten to twelve flowers per umbel; semi-double pure white flowers; and good weather tolerance.

Description

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Geranium plant, botanically known as Pelargonium×hortorum, and hereinafter referred to by the name `Merisnow`.
The new Geranium is a product of a planned breeding program conducted by the inventor in Wateringen, The Netherlands. The objective of the breeding program was to develop compact Geranium varieties with semi-double flowers, fast rooting, good flower form, tolerance to Botrytis, weather resistance, compact and pendant growth habit, and attractive flower and foliage colors.
The new Geranium originated from a cross made by the inventor of two proprietary seedling selections identified as code number A111 as the female, or seed, parent and code number A234 as the male, or pollen, parent. The new Geranium was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Wateringen, The Netherlands, in June, 1995.
Compared to plants of the male parent, plants of the new Geranium are taller. Additionally, plants of the new Geranium have a distinct zonation pattern on the foliage whereas plants of the male parent are devoid of a zonation pattern.
Compared to plants of the female parent, plants of the new Geranium are more compact and have a less distinct zonation pattern on the leaves. Additionally, plants of the new Geranium have semi-double flowers whereas plants of the female parent have single flowers.
Asexual reproduction of the new Geranium by terminal cuttings taken at Wateringen, The Netherlands, 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 `Merisnow`. These characteristics in combination distinguish `Merisnow` as a new and distinct Geranium:
1. Rounded and compact growth habit.
2. Moderate growth rate and vigor.
3. Fast rooting.
4. Dark green foliage color with distinct zonation pattern.
5. Numerous peduncles with ten to twelve flowers per umbel.
6. Semi-double pure white flowers.
7. Good weather tolerance.
The new Geranium can be compared to the Geranium variety `Fisalb` (disclosed in U.S. Plant Pat. No. 9,761). Compared to plants of `Fisalb`, plants of the new Geranium flower earlier, have shorter and more numerous peduncles, and have a less intense zonation pattern on the foliage.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Geranium, 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 `Merisnow`.
The photograph at the top of the second sheet comprises a close-up view of a typical flower of `Merisnow`.
The photographs at the bottom of the second sheet comprises a close-up view of typical leaves, upper surface is on the left and lower surface is on the right. Foliage and flower colors in the photograph may appear different from the actual colors due to light reflectance.
DETAILED BOTANICAL DESCRIPTION
The new Geranium 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 Wateringen, The Netherlands, under commercial practice in a glass-covered greenhouse with day temperatures of 20° C. and night temperatures of 18° C. and light levels of 450 W/m.sup. 2.
