Abstract

A new and distinct cultivar of Alstroemeria plant named ‘Tescreda Improved’, characterized by its upright and uniformly mounding plant habit; sturdy and strong plants; moderately vigorous growth habit; white and red purple-colored flowers with short pedicels; and good garden performance.

Description

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘TESCREDA IMPROVED’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, grown typically as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Tescreda Improved’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to create new potted garden Alstroemeria plants that flower continuously and have attractive leaf and flower coloration.

The new Alstroemeria plant is a naturally-occurring branch mutation of Alstroemeria hybrida ‘Tescreda’, not patented. The new Alstroemeria plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘Tescreda’ in a controlled greenhouse environment in Heerhugowaard, The Netherlands in June, 2008.

Asexual reproduction of the new Alstroemeria plant by root divisions in a controlled greenhouse environment in Heerhugowaard, The Netherlands since September, 2008 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Tescreda Improved’. These characteristics in combination distinguish ‘Tescreda Improved’ as a new and distinct Alstroemeria plant:

- 1. Upright and uniformly mounding plant habit.
- 2. Sturdy and strong plants; moderately vigorous growth habit.
- 3. White and red purple-colored flowers with short pedicels.
- 4. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the mutation parent, ‘Tescreda’. Plants of the new Alstroemeria differ from plants of ‘Tescreda’ in the following characteristics:

- 1. Plants of the new Alstroemeria are larger and more vigorous than plants of ‘Tescreda’.
- 2. Plants of the new Alstroemeria have larger flowers than plants of ‘Tescreda’.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Teswhitin’, not patented. In side-by-side comparisons, plants of the new Alstroemeria differ primarily from plants of ‘Teswhitin’ in flower color as plants of ‘Teswhitin’ have white-colored flowers with more and longer stripes on the tepals.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Tescreda Improved’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown during the winter in 4.6-liter containers in a glass-covered greenhouse in Kudelstaart, The Netherlands. During the production of the plants, day temperatures ranged from 14° C. to 16° C. and night temperatures ranged from 12° C. to 14° C. Plants were 15 weeks old when the photograph and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
