Description

Botanical classification/cultivar designation: Mandevilla sanderi cultivar Monproud.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Mandevilla plant, botanically known as Mandevilla sanderi, and hereinafter referred to by the name ‘Monproud’.

The new Mandevilla is a naturally-occurring branch mutation of the Mandevilla sanderi cultivar Red Riding Hood, not patented. The new Mandevilla was discovered and selected by the Inventor in August, 1999 in a controlled environment in Azusa, Calif., from within a population of plants of the cultivar Red Riding Hood.

Asexual reproduction of the new cultivar by tissue culture in a laboratory in Azusa, Calif., since September, 2000, has shown that the unique features of this new Mandevilla are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Monproud have 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 traits have been repeatedly observed and are determined to be the unique characteristics of ‘Monproud’. These characteristics in combination distinguish ‘Monproud’ as a new and distinct cultivar of Mandevilla:

1. Vining plant habit.

2. Compact growth habit, short internodes.

3. Variegated leaves; developing foliage, red and green; fully expanded foliage, pale yellow, green and grayed green.

4. Red purple-colored flowers with yellow-colored throats.

Plants of the new Mandevilla are most similar to plants of the parent, the cultivar Red Riding Hood. In side-by-side comparisons conducted in Azusa, Calif., plants of the new cultivar differed from plants of the cultivar Red Riding Hood in the following characteristics:

1. Plants of the new Mandevilla were more compact with shorter internodes than plants of the cultivar Red Riding Hood.

2. Leaves of plants of the new Mandevilla were variegated whereas leaves of plants of the cultivar Red Riding Hood were solid green in color.

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. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Mandevilla.

The photograph at the top of the sheet comprises a side perspective view of a typical plant of ‘Monproud’ grown in a container.

The photograph at the bottom of the sheet comprises a close-up view of typical flowers and leaves of ‘Monproud’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the above-mentioned photographs and description were about 2.5 years old when the photographs and description were taken. Plants were grown in seven-gallon containers and under commercial production conditions in an outdoor nursery in Azusa, Calif. during the summer. During the production of the plants, day temperatures ranged from 21 to 29° C. and night temperatures ranged from 7 to 16° C.
