Abstract

A new and distinct cultivar of Pentas plant named ‘Bismarck Pink’, characterized by its upright and somewhat outwardly spreading plant habit; short internodes and freely branching habit; dense and bushy growth habit; small, dark green-colored leaves; freely flowering habit; and large pink-colored flowers with white-colored throats arranged in large terminal corymbs that are positioned above the foliage.

Description

Botanical classification/cultivar designation: Pentas lanceolata cultivar Bismarck Pink.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Pentas plant, botanically known as Pentas lanceolata, and hereinafter referred to by the name ‘Bismarck Pink’.
The new Pentas is a product of a planned breeding program conducted by the Inventor in Pintung, Taiwan. The objective of the breeding program was to develop new moderately tall and freely branching Pentas cultivars with numerous large flowers and attractive flower and foliage coloration.
The new Pentas originated from a cross-pollination made by the Inventor during the summer of 1995 of two unidentified proprietary selections of Pentas lanceolata, not patented. The cultivar Bismarck Pink was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Pintung, Taiwan in 1996.
Asexual reproduction of the new cultivar by terminal cuttings in Pintung, Taiwan, since the summer of 1996, has shown that the unique features of this new Pentas 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 ‘Bismarck Pink’. These characteristics in combination distinguish ‘Bismarck Pink’ as a new and distinct Pentas cultivar:
    • 1. Upright and somewhat outwardly spreading plant habit.
    • 2. Short internodes and freely branching habit; dense and bushy growth habit.
    • 3. Small, dark green-colored leaves.
    • 4. Freely flowering habit.
    • 5. Large pink-colored flowers with white-colored throats arranged in large terminal corymbs that are positioned above the foliage.
Plants of the new Pentas differ primarily from plants of the parent selections in the following characteristics:
    • 1. Plants of the new Pentas are taller than plants of the parent selections.
    • 2. Plants of the new Pentas have larger inflorescences with larger flowers than plants of the parent selections.
The new Pentas can be compared to the Pentas lanceolata cultivar Butterfly, not patented. However, in side-by-side comparisons conducted in Pintung, Taiwan, plants of the new Pentas differed from plants of the cultivar Butterfly in the following characteristics:
    • 1. Plants of the new Pentas had smaller, more rugose and darker green-colored leaves than plants of the cultivar Butterfly.
    • 2. Plants of the new Pentas had larger flowers with thicker petals than plants of the cultivar Butterfly.
    • 3. Flowers of plants of the new Pentas were longer lasting than flowers of plants of the cultivar Butterfly.
    • 4. Plants of the new Pentas did not set seed whereas plants of the cultivar Butterfly set seed.
The new Pentas can also be compared to the Pentas lanceolata cultivar New Look Graffiti, not patented. However, in side-by-side comparisons conducted in Pintung, Taiwan, plants of the new Pentas differed from plants of the cultivar New Look Graffiti in the following characteristics:
    • 1. Plants of the new Pentas were taller and more vigorous than plants of the cultivar New Look Graffiti.
    • 2. Plants of the new Pentas had smaller and darker-green colored leaves than plants of the cultivar New Look Graffiti.
    • 3. Plants of the new Pentas had larger inflorescences and larger flowers than plants of the cultivar New Look Graffiti.
    • 4. Flowers of plants of the new Pentas were longer lasting than flowers of than plants of the cultivar New Look Graffiti.
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 Pentas.
The photograph at the bottom of the sheet comprises a side perspective view of a flowering plant of ‘Bismarck Pink’ grown in a container.
The photograph at the top of the sheet is close-up view of typical flowers and leaves of ‘Bismarck Pink’.
 DETAILED BOTANICAL DESCRIPTION
Plants of the cultivar Bismarck Pink have not been observed under all possible environmental consitions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice in a polycarbonate-covered greenhouse during the winter. During the production of the plants, day temperatures ranged from 21 to 30° C., night temperatures ranged from 16 to 18° C. and light levels ranged from 5,000 to 9,000 foot-candles. Rooted young plants were pinched once and then planted in 15.25-cm containers. Plants had been growing for about 31 weeks when the photographs and the description were taken. 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.
