A new and distinct Calibrachoa plant named ‘INTA 06575’, characterized by its compact, upright to outwardly spreading and mounding to eventually trailing plant habit; vigorous growth habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; purple-colored flowers with yellow-colored throats; and good garden performance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoaplant, botanically known asCalibrachoa caesia×Calibrachoa hybridaand hereinafter referred to by the name ‘INTA 06575’.

The newCalibrachoaplant is a product of a planned breeding program conducted by the Inventors in Hurlingham, Province of Buenos Aires, Argentina. The objective of the breeding program is to create new vigorous and freely-floweringCalibrachoaplants with unique and attractive flower coloration and good garden and summer performance.

The newCalibrachoaplant originated from a cross-pollination conducted by the Inventors in Hurlingham, Province of Buenos Aires, Argentina in September, 2005 of a proprietary selection ofCalibrachoa caesiaidentified as code number 2003092512, not patented, as the female, or seed, parent with the proprietary selection ofCalibrachoa hybridareferred to as ‘Dark Blue’, not patented, as the male, or pollen, parent. The newCalibrachoaplant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hurlingham, Province of Buenos Aires, Argentina in October, 2006.

Asexual reproduction of the newCalibrachoaplant by vegetative terminal cuttings in a controlled greenhouse environment in Hurlingham, Province of Buenos Aires, Argentina since October, 2006 has shown that the unique features of this newCalibrachoaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘INTA 06575’. These characteristics in combination distinguish ‘INTA 06575’ as a new and distinctCalibrachoaplant:1. Compact, upright to outwardly spreading and mounding to eventually trailing plant habit.2. Vigorous growth habit.3 Freely branching habit; dense and bushy appearance.4. Early and freely flowering habit.5. Purple-colored flowers with yellow-colored throats.6. Good garden performance.

The newCalibrachoaplant can be compared to plants of the female parent selection. Plants of the newCalibrachoadiffer primarily from plants of the female parent selection in the following characteristics:1. Plants of the newCalibrachoaare more outwardly spreading than and not as upright as plants of the female parent selection.2. Plants of the newCalibrachoahave smaller leaves than plants of the female parent selection.3. Plants of the newCalibrachoahave larger flowers than plants of the female parent selection.

The newCalibrachoaplant can be compared to plants of the male parent selection. Plants of the newCalibrachoadiffer primarily from plants of the male parent selection in the following characteristics:1. Plants of the newCalibrachoaare taller than plants of the male parent selection.2. Plants of the newCalibrachoahave longer internodes than plants of the male parent selection.3. Plants of the newCalibrachoaand the male parent selection differ slightly in flower color as plants of the male parent selection have purple violet-colored flowers.4. Plants of the newCalibrachoahave better garden performance than plants of the male parent selection.

Plants of the newCalibrachoacan be compared to plants of theCalibrachoasp. ‘USCALI11’, disclosed in U.S. Plant Pat. No. 14,968. In side-by-side comparisons conducted in Bonsall, Calif., plants of the newCalibrachoadiffered primarily from plants of ‘USCALI11’ in the following characteristics:1. Plants of the newCalibrachoawere shorter than plants of ‘USCALI11’.2. Plants of the newCalibrachoawere more vigorous than plants of ‘USCALI11’.3. Plants of the newCalibrachoahad smaller flowers than plants of ‘USCALI11’.4. Plants of the newCalibrachoaand ‘USCALI11’ differed in flower color as plants of ‘USCALI11’ had light red purple-colored flowers.

Plants of the newCalibrachoacan also be compared to plants of theCalibrachoasp. ‘Caltrapi’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the newCalibrachoadiffered primarily from plants of ‘Caltrapi’ in the following characteristics:1. Plants of the newCalibrachoawere more mounding than and not as flat as plants of ‘Caltrapi’.2. Plants of the newCalibrachoawere more vigorous than plants of ‘Caltrapi’.3. Plants of the newCalibrachoahad smaller flowers than plants of ‘Caltrapi’.
