Abstract

A new Saxifraga plant named ‘Rocklarwhi,’ particularly distinguished by its completely white flower color, very big flower size, early flowering, and compact plant habit.

Description

Latin name of the genus and species of the plant claimed: Saxifraga×arendsii.
Varietal denomination: ‘Rocklarwhi’.
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 pure white flower color, very large flowers, and is very early flowering.
The new Saxifraga is propagated by cuttings resulting from a single seedling. This seedling originated from an open pollination of a white flowering selection identified as number ‘D571’ (not patented). This pollination took place in April 2003 in Enkhuizen, Netherlands. The seeds were sown in August 2003. The seedling was selected in March 2004 in Enkhuizen.
The present cultivar has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands, since 2004. The distinctive characteristics of this new Saxifraga are stable and reproduced true to type in successive generations of asexual reproduction. It takes 21 to 27 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 reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 28 week old plants. The instant plant was grown in an 11 cm container in a plastic tunnel.
Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London, edition 2001.
Plants of the new Saxifraga differ primarily from the plants of the originator ‘D571’ in the following characteristics:
Plants of the new variety have completely white flowers and a compact growth habit, whereas plants of ‘D571’ have white flowers with pink edges, and a loose growth habit. The flowers of the new variety have almost double the size of the flowers of ‘D571.’ Plants of the new variety start flowering two weeks earlier than the plants of ‘D571’.
