Abstract

A new Saxifraga plant, particularly distinguished by its rose flower color, early flowering and compact plant habit.

Description

Latin name of the genus and species of the plant claimed: Saxifraga×arendsii.
Varietal denomination: ‘Rockrose’.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new distinct cultivar of Saxifraga, botanically known as Saxifraga×arendsii.
The new Saxifraga is a product of a planned breeding program conducted in Enkhuizen, Netherlands. The new Saxifraga cultivar has a compact plant habit, a rose flower color and an early flowering.
The new Saxifraga is propagated by cuttings resulting from a single seedling. This seedling originates from a rose flowering selection in Saxifraga×arendsii ‘Blutenteppich’ (not patented), identified as number ‘D652.’ This selection was made through three cycles of half sib selection. The selection was done in the period April 2001 until March 2003 in Enkhuizen, The Netherlands. The seedling was selected in March 2003 in Enkhuizen.
The present cultivar has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, since 2003. The distinctive characteristics of this new Saxifraga are stable and reproduced true to type in successive generations of asexual reproduction. It takes 23 to 29 weeks to produce a finished plant, depending on the temperature.
The new Saxifraga plant is a perennial in all climatic zones in the US.
DESCRIPTION OF THE DRAWING
The new Saxifraga plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color showing being as true as can be reasonably obtained by conventional photographic procedures.
 DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of this new Saxifraga. The data which defines these characteristics were collected from asexual reproduction carried out in Enkhuizen, Netherlands. The plant history was taken on plants of 30 weeks old. The instant plant was grown in an 11 cm container in a plastic tunnel.
Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
Plants of the new Saxifraga differ primarily from the plants of the originator ‘Blutenteppich’ in the following characteristics:
Plants of the new variety have uniform rose flowers and a compact growth habit, whereas plants of ‘Blutenteppich’ have flowers varying in color from light rose to dark red, and a loose growth habit.
