Plectranthus plant named ‘K111201’

Abstract

A new and distinct cultivar of Plectranthus plant named ‘K111201’, characterized by having more compact, freely branching plant habit; shorter production time; vigorous growth habit; large almost white flowers; upright main lip of corolla; and shiny green foliage.

Description

Latin name of genus and species of the plant claimed: Plectranthus hybrida.

Variety denomination: K111201.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Plectranthus plant, botanically known as Plectranthus hybrida (Family Lamiaceae), hereinafter referred to by the name ‘K111201’.

The new Plectranthus, ‘K111201’, is a new and distinct mutation (sport), detected in a production batch of Plectranthus hybrida, ‘P000603’ (U.S. Plant patent application Ser. No. 10/716,659) by the Inventor, Gert Johannes Brits, in Kortegaard, Nörre Söby, Denmark. The objective of the breeding program in which the mutation was detected is to improve upon the Plectranthus varieties currently available, such as the cultivar ‘Edelbau’ (unpatented), by developing a Plectranthus variety with a more compact growth habit, larger flowers and improved vigor. The new cultivar has been produced only by vegetative propagation (cuttings). The Inventor selected the new Plectranthus cultivar on the basis of its compact growth habit, larger flowers and increased vigor.

Asexual reproduction of the new cultivar by terminal cuttings taken and propagated, has shown that each of the progenies exhibit characteristics identical to the original plant. These characteristics have been shown to come true to form through many generations of asexual propagation under commercial production conditions in Nr. Lyndelse, Fyn, Denmark. The present invention has been tested under lighted greenhouse conditions and for keeping quality in a consumer environment, but may differ in various aspects if grown under different conditions.

SUMMARY OF THE INVENTION

Plants of the cultivar ‘K111201’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘K111201’. These characteristics in combination distinguish ‘K111201’ as a new and distinct cultivar:

• • 1. White flowers with purple spots, upright corolla lip;
  • 2. Compact and freely branching plant habit;
  • 3. Shorter production time, 14 weeks compared to the typical 16 weeks; and
  • 4. Shiny green foliage.

Side-by-side comparisons between the instant plant and the “mother” cultivar ‘P000603’ were conducted by the Inventor. Plants of ‘K111201’ differ from ‘P000603’ in the following characteristics:

• • 1. Plants of ‘K111201’ have larger, almost white flowers with pink to purple spots, while plants of ‘P000603’ have slightly smaller pink flowers.
  • 2. Plants of ‘K111201’ have better branching growth habit and shiner foliage than plants of ‘P000603’.
  • 3. Plants of ‘K111201’ have a faster growth rate than plants of ‘P000603’.
  • 4. Plants of ‘K111201’ have an upright main lip of corolla.
