Abstract

A new and distinct cultivar of Tibouchina plant named ‘Grue-TiB 05’, characterized by its upright plant habit; freely branching habit; and purple-colored flowers.

Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Tibouchina organensis cultivar Grue-TiB 05.
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Tibouchina plant, botanically known as Tibouchina organensis, and hereinafter referred to by the name ‘Grue-TiB 05’.
The new Tibouchina is a product of a induced mutation breeding program conducted by the Inventor in Lünen, Germany. The objective of the program is to create new Tibouchinas with different plant forms and sizes.
The new Tibouchina is an induced mutation of an unnamed selection of Tibouchina organensis, not patented. Mutations were induced by exposing unrooted cuttings of the unnamed Tibouchina selection to gamma radiation. The new Tibouchina was discovered and selected by the Inventor as a single flowering plant within a population of irradiated plants of the unnamed Tibouchina selection in 1999 in a controlled environment in Lünen, Germany. The new Tibouchina was selected on its plant form and growth habit.
Asexual reproduction of the new cultivar by cuttings taken in a controlled environment in Lünen, Germany since 1999, has shown that the unique features of this new Tibouchina are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Grue-TiB 05 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 ‘Grue-TiB 05’. These characteristics in combination distinguish ‘Grue-TiB 05’ as a new and distinct cultivar:
1. Upright plant habit.
2. Freely branching habit.
3. Purple-colored flowers.
In side-by-side comparisons conducted in Lünen, Germany, plants of the New Tibouchina differed from plants of the parent selection in the following characteristics:
1. Plants of the new Tibouchina were more freely branching than plants of the parent selection.
2. Plants of the new Tibouchina had shorter internodes than plants of the parent selection.
Compared to plants of the Tibouchina cultivar Grue-TiB 01, disclosed in U.S. Plant patent application Ser. No. 10/094,274, plants of the new Tibouchina are taller, more upright, and have larger leaves. Compared to plants of the Tibouchina cultivar Grue-TiB 02, disclosed in U.S. Plant patent application Ser. No. 10/094,327, plants of the new Tibouchina are taller, more upright, and have larger leaves. Compared to plants of the Tibouchina cultivar Grue-TiB 03, disclosed in U.S. Plant patent application Ser. No. 10/094,336, plants of the new Tibouchina are taller, more upright, have larger leaves, and have larger flowers. Compared to plants of the Tibouchina cultivar Grue-TiB 04, disclosed in U.S. Plant patent application Ser. No. 10/094,273, plants of the new Tibouchina are taller, more upright, are not as freely branching, and have smaller flowers.
Plants of the new Tibouchina can be compared to plants of the Tibouchina urvilleana Rich Blue Sun, not patented. In side-by-side comparisons conducted in Lünen, Germany, plants of the new Tibouchina differed from plants of the cultivar Rich Blue Sun in the following characteristics:
1. Plants of the new Tibouchina were more freely branching than plants of the cultivar Rich Blue Sun.
2. Plants of the new Tibouchina had shorter internodes than of the cultivar Rich Blue Sun.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Tibouchina. The photograph comprises a side perspective view of a typical flowering plant of ‘Grue-TiB 05’.
