ABSTRACT:
Botanical classification/cultivar designation:
Calathea roseo picta
cultivar ‘Tanja’.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of
Calathea
plant, botanically known as
Calathea roseo picta,
and hereinafter referred to by the namae ‘Tanja’.
The new
Calathea
is a naturally-occurring whole plant mutation of the
Calathea roseo picta
cultivar Rosy, disclosed in U.S. Plant Pat. No. 8,836. The new
Calathea
was discovered and selected by the Inventor as a single plant from within a population of plants of the cultivar Rosy in a controlled environment in Schipluiden, The Netherlands during the Fall, 2000. The selection of this plant was based on its attractive leaf coloration.
Asexual reproduction of the new cultivar by cuttings taken at Schipluiden, The Netherlands since the Fall, 2000, has shown that the unique features of this new
Calathea
are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Tanja have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Tanja’. These characteristics in combination distinguish ‘Tanja’ as a new and distinct cultivar:
1. Upright and broad outwardly spreading growth habit.
2. Leaf shape, broadly ovate.
3. Upper leaf surfaces grayed green in color with dark green-colored margins.
4. Lower leaf surfaces dark purple in color.
Plants of the new
Calathea
are most similar to plants of the parent cultivar, Rosy. However plants of the new
Calathea
differ primarily from plants of the cultivar Rosy in leaf coloration as plants of the cultivar Rosy have pink and green-colored leaves.
