Claims
It is claimed:
1. A new and distinct Tradescantia plant named `Nanouk` as
illustrated and described.
Description
Botanical designation: Tradescantia albiflora.
Cultivar denomination: `NANOUK`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of
Tradescantia plant, botanically known as Tradescantia albiflora and
hereinafter referred to by the name `Nanouk`.
The new Tradescantia plant is a product of a planned breeding
program conducted by the Inventor in Sappemeer, The Netherlands.
The objective of the breeding program was to create new compact
Tradescantia plants with attractive flower coloration and good
performance.
The new Tradescantia plant originated from a cross-pollination in
2012 in Sappemeer, The Netherlands, of two unnamed seedling
selections of Tradescantia albiflora, not patented. The new
Tradescantia plant was discovered and selected by the Inventor as a
single flowering plant from within the progeny of the stated
cross-pollination in a controlled environment in Sappemeer, The
Netherlands.
Asexual reproduction of the new Tradescantia plant by terminal
cuttings in a controlled environment in Sappemeer, The Netherlands
since March, 2013 has shown that the unique features of this new
Tradescantia plant are stable and reproduced true to type in
successive generations.
SUMMARY OF THE INVENTION
Plants of the new Tradescantia have not been observed under all
possible combinations of environmental conditions and cultural
practices. 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 `Nanouk`. These
characteristics in combination distinguish `Nanouk` as a new and
distinct Tradescantia plant: 1. Compact and upright to broadly
spreading plant habit. 2. Strong and healthy leaves. 3. Light
purple, green and greyed green-colored leaves. 4. Good
interiorscape performance.
Plants of the new Tradescantia and the parent selections differ
primarily in leaf color as plants of the parent selections have
white and green-colored leaves.
Plants of the new Tradescantia can be compared to plants of the
Tradescantia spathacea `Tricolor`, not patented. In side-by-side
comparisons, plants of the new Tradescantia and `Tricolor` differ
primarily in leaf shape as plants of new Tradescantia have shorter
and more rounded leaves than plants of `Tricolor`.
Plants of the new Tradescantia can also be compared to plants of
the Tradescantia albiflora `Albovittata`, not patented. In
side-by-side comparisons, plants of the new Tradescantia and
`Albovittata` differ primarily in leaf color as plants of
`Albovittata` have white and green-colored leaves.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Tradescantia plant 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 Tradescantia plant.
The photograph on the first sheet comprises a side perspective view
of a typical plant of `Nanouk` grown in a container.
The photograph on the second sheet is a close-up view of a typical
plant of `Nanouk`.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations,
measurements and values describe plants grown in 12-cm containers
during the winter in a glass-covered greenhouse in Sappemeer, The
Netherlands and under cultural practices typical of commercial
Tradescantia production. During the production of the plants, day
temperatures ranged from 20.degree. C. to 25.degree. C. and night
temperatures ranged from 18.degree. C. to 20.degree. C. Plants were
18 weeks old when the photographs and description were taken. In
the following description, color references are made to The Royal
Horticultural Society Colour Chart, 2015 Edition, except where
general terms of ordinary dictionary significance are used.
