Abstract

A new and distinct cultivar of Pentas plant named ‘Lava White’, characterized by its upright and somewhat outwardly spreading plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; and white-colored flowers arranged in large terminal corymbs that are positioned above the foliage.

Description

Botanical classification/cultivar designation: Pentas lanceolata cultivar Lava White.
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 ‘Lava White’.
The new Pentas is a product of a planned breeding program conducted by the Inventor in Rheinfelden, Germany. The objective of the breeding program was to develop new moderately tall Pentas cultivars with numerous flowers and attractive flower and foliage coloration.
The new Pentas originated from a cross-pollination made by the Inventor during the summer of 1999 of two unnamed proprietary selections of Pentas lanceolata, not patented. The cultivar Lava White was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Rheinfelden, Germany.
Asexual reproduction of the new cultivar by terminal cuttings taken in Rheinfelden, Germany, 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 ‘Lava White’. These characteristics in combination distinguish ‘Lava White’ as a new and distinct Pentas cultivar:
1. Upright and outwardly spreading plant habit.
2. Freely branching habit.
3. Dark green-colored leaves.
4. Freely flowering habit.
5. White-colored flowers 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 more compact than plants of the parent selections.
2. Plants of the new Pentas have larger flowers and larger inflorescences than plants of the parent selections.
3. Flowers of plants of the new Pentas are not fragrant whereas flowers of plants of the parent selections are fragrant.
The new Pentas can be compared to the Pentas lanceolata cultivar New Look Red, not patented. However, in side-by-side comparisons conducted in Rheinfelden, Germany, plants of the new Pentas differed from plants of the cultivar New Look Red in the following characteristics:
1. Plants of the new Pentas were taller and more vigorous than plants of the cultivar New Look Red.
2. Plants of the new Pentas were more uniform than plants of the cultivar New Look Red.
3. Flowers of plants of the new Pentas and the cultivar New Look Red differed in flower coloration.
The new Pentas can also be compared to the Pentas lanceolata cultivar New Look White, not patented. However, in side-by-side comparisons conducted in Rheinfelden, Germany, plants of the new Pentas differed from plants of the cultivar New Look White in the following characteristics:
1. Plants of the new Pentas were taller and more vigorous than plants of the cultivar New Look White.
2. Plants of the new Pentas had larger inflorescences than plants of the cultivar New Look White.
3. Plants of the new Pentas were more uniform than plants of the cultivar New Look White.
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 top of the sheet comprises a side perspective view of a flowering plant of ‘Lava White’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of typical flowers, inflorescences and leaves of ‘Lave White’.
DETAILED BOTANICAL DESCRIPTION
Plants of the cultivar Lava White 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 aforementioned photographs and following observations and measurements describe plants grown in Lompoc, Calif., under commercial practice in a polycarbonate-covered greenhouse during the summer. During the production of the plants, day temperatures ranged from 21 to 27° 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-cm containers. Plants had been growing for about 16 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.
