Abstract

A new Aster plant named ‘Syast Draip’ particularly distinguished by the upright, rounded and freely branching growth habit, dark green foliage, with violet colored ray florets.

Description

Latin name of the genus and species of the plant claimed: Symphyotrichum hybrid.

Varietal denomination: ‘Syast Draip’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Aster, botanically know as Symphyotrichum hybrid, and hereinafter referred to by the variety name ‘Syast Draip’.

‘Syast Draip’ is a product of a planned breeding program. The new cultivar ‘Syast Draip’ has upright, rounded and freely branching growth habit, dark green foliage, with violet colored ray florets.

‘Syast Draip’ originates from an open pollinated hybridization made in August 2003 in a controlled breeding program in Salinas, Calif. The female parent was ‘Yodaydream’, U.S. Plant Pat. No. 16,366, with lighter violet flowers, larger disc area, larger plant habit, and slower natural season flowering response. The resultant seed was sown in April 2004 in Alva, Fla.

‘Syast Draip’ was selected as one flowering plant within the progeny of the stated cross in the September 2004 in a controlled environment in Alva, Fla.

The first act of asexual reproduction of ‘Syast Draip’ was accomplished when vegetative cuttings were taken from the initial selection in October, 2004 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in October 2004, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Syast Draip’ are firmly fixed and are retained through successive generations of asexual reproduction.

A Plant Breeder's Right for this cultivar has been applied for in Canada on Mar. 19, 2010 (No. 10-6888). ‘Syast Draip’ has not been made publicly available more than one year prior to the filing of this application.

‘Syast Draip’ 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.

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 ‘Syast Draip’ 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 flower.

DETAILED BOTANICAL DESCRIPTION

The plant used for the photographs was about 12 weeks old, grown in a 1 gallon pot in an outdoor trial in Gilroy, Calif.

The plant descriptions and measurements were taken in Gilroy, Calif. in May 2010 under natural light. Plants were grown under conditions which approximate those generally used for potted Aster trials in a greenhouse. These plants used in the descriptions were about 10 weeks old.
