Abstract

A new Saxifraga plant named ‘SAXZ0009’ particularly distinguished by the large red-purple flowers on short peduncles held straight just above the plant with a long flowering season and good plant vigor.

Description

Latin name of the genus and species of the plant claimed: Saxifraga×arendsii.

Varietal denomination: ‘SAXZ0009’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Saxifraga, botanically known as Saxifraga×arendsii, and hereinafter referred to by the variety name ‘SAXZ0009’.

‘SAXZ0009’ is a product of a planned breeding program. The new cultivar ‘SAXZ0009’ has large red-purple flowers on short peduncles held straight just above the plant with a long flowering season and good plant vigor.

‘SAXZ0009’ originates from a hybridization made in a greenhouse in April 2007 in Enkhuizen, The Netherlands. The female parent was an unpatented, proprietary plant identified as ‘J1460-1’ ‘J1460-1’ has white flower color, larger flower size and is earlier to flower than ‘SAXZ0009.

The male parent of ‘SAXZ0009’ was an unpatented, proprietary plant identified as ‘H1048-52’. ‘H1048-52’ has red flower color, smaller flower size and is later to flower compared to ‘SAXZ0009’. The resultant seed was sown in August 2007 in Enkhuizen, The Netherlands.

‘SAXZ0009’ was selected as one flowering plant within the progeny of the stated cross in March 2008 in a greenhouse in Enkhuizen, The Netherlands.

The first act of asexual reproduction of ‘SAXZ0009’ was accomplished when vegetative cuttings were propagated from the initial selection in the March 2008 in a greenhouse in Enkhuizen, The Netherlands.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated March 2008 in Enkhuizen, The Netherlands, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘SAXZ0009’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘SAXZ0009’ 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 Jun. 7, 2012. ‘SAXZ0009’ 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 Saxifraga as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawings show typical flower and foliage characteristics of ‘SAXZ0009’ with colors being as true as possible with an illustration of this type.

The photographic drawings show in FIG. 1 a flowering plant of the new variety and in FIG. 2 a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in Gilroy, Calif. under natural light in March 2012. These plants were approximately 24 weeks old and were growing in 1 gallon pots in shade-house trials. The plants used for the photographs were about 28 weeks old growing in Enkhuizen, The Netherlands and the photographs were taken in March 2012.
