Abstract

A new Petunia plant named ‘Pic Amthe’ particularly distinguished by the small purple to purple-violet colored flowers, good floriferousness, slightly yellow-green foliage, initially semi-compact and then an outwardly spreading and somewhat upright plant habit, good vigor, well branched, with early and continuous flowering response.

Description

Latin name of the genus and species of the plant claimed: Petunia hybrida.

Varietal denomination: ‘Pic Amthe’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Petunia, botanically known as Petunia hybrida, and hereinafter referred to by the variety name ‘Pic Amthe.’

‘Pic Amthe’ is a product of a planned breeding program. The new cultivar has small purple to purple-violet colored flowers, good floriferousness, slightly yellow-green foliage, initially semi-compact and then an outwardly spreading and somewhat upright plant habit, good vigor, well branched, with early and continuous flowering response.

‘Pic Amthe’ originated from a hybridization made in August 2004 in a controlled breeding environment in Gilroy, Calif. The seed was sown in February 2005. The female parent was the proprietary plant designated ‘1691-1,’ unpatented, with blue-pink flower color, less vigor and a more open plant habit.

The male parent of ‘Pic Amthe’ is the commercially available variety identified as ‘MP 209,’ (U.S. Plant Pat. No. 16,439) with a rose colored flower. ‘MP 209’ is earlier to flower, has longer branches, and shorter peduncles than ‘Pic Amthe.’

‘Pic Amthe’ was selected as one flowering plant within the progeny of the stated cross in May 2005 in a controlled environment in Gilroy, Calif.

The first act of asexual reproduction of ‘Pic Amthe’ was accomplished when vegetative cuttings were propagated from the initial selection in May 2005 in a controlled environment in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in May 2005, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Pic Amthe’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Pic Amthe’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Jan. 30, 2009. ‘Pic Amthe’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Petunia as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Pic Amthe’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety, and a close-up of the flowers, growing in a greenhouse in the winter in Gilroy, Calif.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in January 2010 under natural light. These plants used in the photograph and descriptions were about 7-9 weeks old, directly grow from tissue culture stock.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
