Description

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

Varietal denomination: ‘Synhen Thefirst’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Aster, botanically known as Aster hybrida, and hereinafter referred to by the variety name ‘Synhen Thefirst’.

‘Synhen Thefirst’ originated from an open-pollinated hybridization made in March 2006 in a controlled breeding environment in Alva, Fla. The female parent was the unpatented, proprietary plant designated ‘AS04-036’ with lavender ray floret color. ‘AS04-036’ has a more compact plant habit with more vigor than ‘Synhen Thefirst’.

‘Synhen Thefirst’ originated from an open-pollinated hybridization made in March 2006 in a controlled breeding environment in Alva, Fla. The female parent was the unpatented, proprietary plant designated ‘AS04-036’ with lavender ray floret color. ‘AS04-36’ has a more compact plant habit with more vigor than ‘Synhen Thefirst’.

The male parent of ‘Synhen Thefirst’ was an unknown plant. The resultant seed was sown in late May 2006. ‘Synhen Thefirst’ was selected as one flowering plant within the progeny of the stated cross in late October 2006 in a controlled environment in Alva, Fla.

The first act of asexual reproduction of ‘Synhen Thefirst’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2006 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in December 2006, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Synhen Thefirst’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Synhen Thefirst’ 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 Oct. 30, 2009 (09-6777). ‘Synhen Thefirst’ 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 Aster as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Synhen Thefirst’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows three flowering potted plants of the new variety growing within one pot and a close-up of the flowers.

 DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in Gilroy, Calif. in May 2010 under natural light. These plants used in the photograph and descriptions were about 12 weeks old. Plants were grown in an 8 inch pot with three plants per pot.

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