Abstract

A distinct cultivar of Plectranthus plant named ‘Limplep 1’, characterized by its upright, mounded and compact plant habit; vigorous and freely branching growth habit; green and creamy white variegated foliage; numerous violet blue-colored flowers on erect flowering spikes; and good garden performance.

Description

Botanical classification/cultivar designation: Plectranthus parviflorus cultivar Limplep 1.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Plectranthus plant, botanically known as Plectranthus parviflorus, and hereinafter referred to by the name ‘Limplep 1’.

The new Plectranthus is a naturally-occurring whole plant mutation of an unnamed selection of Plectranthus parviflorus, not patented. The new Plectranthus was discovered and selected by the Inventor as a single plant from within a population of plants of the parent selection in a controlled environment in Rochedale, Queensland, Australia in 2000.

Asexual reproduction of the new cultivar by cuttings taken in a controlled environment in Brisbane, Queensland, Australia since 2001, has shown that the unique features of this new Plectranthus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Limplep 1 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture 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 ‘Limplep 1’. These characteristics in combination distinguish ‘Limplep 1’ as a new and distinct cultivar of Plectranthus:

- 1. Upright, mounded and compact plant habit.
- 2. Vigorous and freely branching growth habit.
- 3. Green and creamy white variegated foliage.
- 4. Numerous violet blue-colored flowers on erect flowering spikes.
- 5. Good garden performance.

Plants of the new Plectranthus are most similar to plants of the parent selection. In side-by-side comparisons conducted in Brisbane, Queensland, Australia, plants of the new Plectranthus differed from plants of the parent selection in the following characteristics:

- 1. Plants of the new Plectranthus had variegated foliage whereas plants of the parent selection had nonvariegated foliage.
- 2. Plants of the new Plectranthus had darker violet blue-colored flowers than plants of the parent selection.

Plants of the new Plectranthus can also be compared to plants of the Plectranthus cultivar P000603, disclosed in U.S. Plant Pat. No. 16,002. Plants of the new Plectranthus differ primarily from plants of the cultivar P000603 in leaf and flower coloration as plants of the cultivar P000603 have dark green-colored leaves and pink-colored flowers.

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 Plectranthus.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Limplep 1’.

The photograph at the top of the sheet comprises a close-up view of a typical leaves and flowers of ‘Limplep 1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in Bonsall, Calif., under commercial practice during the summer in an outdoor nursery with day temperatures ranging from 18 to 35° C. and night temperatures ranging from 10 to 21° C. Plants were grown with one rooted cutting per 10-cm container for about seven weeks.
