USPP13027P2 - Geranium plant named ‘Bonito’ - Google Patents

Abstract

Geranium ‘Bonito’ is a new and distinct cultivar of geranium plant, particularly characterized by the combined features of dark-purple, white edged, double flowers, small, semi-spherical umbels, deep green, zoned foliage, weak growth with moderate branching, resulting in medium tall, somewhat open plant habit, and medium to late spring flowering response.

Description

BACKGROUND OF THE INVENTION

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

‘Bonito’ originated from a naturally occurring mutation in the variety ‘Barbe Blue’ that was discovered by C. van Holsteijn in a greenhouse in Honselersdijk, Netherlands, in May 1994.

An apparently completely mutated plant developing white bordered flowers was discovered among a group of flowering pot plants of the parent variety. The parent variety ‘Barbe Blue’ was characterized by deep purple flower color, small, relatively dark green foliage, and compact growth habit.

Shoot tips of the mutated plant were taken for propagation by the inventor in Honselersdijk during the summer of 1994. The resulting plants were carefully examined for deviations, and proved to be uniform for the new characteristic.

Horticultural examination of plants grown from the plant initiated in the spring of 1998 in Hillscheid, Germany, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Bonito’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Bonito’ with colors being as true as possible with illustrations of this type. The photograph is a close view of a flowering branch with flowers, buds, and leaves.

The measurements were taken in Langley, Canada, on Jun. 15, 1999, 12 weeks after planting of rooted cuttings into 15 cm pots. The plants had not been pinched.

In the following description color references are made to The Royal Horticultural Society Colour Chart. The color values were determined indoors from flowers developed in a greenhouse in May 1999 in Hillscheid, Germany.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Bonito’, which in combination distinguish this geranium as a new and distinct cultivar:

1. Deep purple colored and white-bordered, double flowers;

2. Small, semi-spherically shaped inflorescence;

3. Small, relatively dark green colored leaves with distinct zonation;

4. Mid season to late flowering;

5. Relatively weak growth and moderate branching ability;

6. Medium tall, somewhat open and slightly trailing plant habit; and

7. Suitable especially for mixed planting in tubs and hanging-baskets.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Bonito’ are the parental variety ‘Barbe Blue’ and the unpatented variety ‘Mexicana’, synonym ‘Rouletta’.

In comparison to ‘Barbe Blue’, ‘Bonito’ has flowers with variegated petals and with a slightly lighter ground color. Furthermore, growth is somewhat more vigorous while other characteristics are fairly close to ‘Barbe Blue’.

In comparison to ‘Mexicana’, ‘Bonito’ has dark purple flowers with black markings on the upper petals whereas ‘Mexicana’ has red-purple flowers, RHS 57C, without the black markings. ‘Bonito’ has medium size flowers whereas ‘Mexicana’ has medium to large size flowers with a diameter of more than 50 mm. The peduncles of ‘Mexicana’ are almost twice as long as those of ‘Bonito’. Lastly, ‘Bonito’ is a relatively compact plant with short internodes while ‘Mexicana’ exhibits vigorous growth, trailing plant habit with long branches and long internodes.

‘Bonito’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

DETAILED BOTANICAL DESCRIPTION
