USPP21098P2 - Sutera plant named ‘Cay Julav’ - Google Patents

Abstract

A new Sutera plant named ‘Cay Julav’ particularly distinguished by large flowers of uniform, lavender color, deep green foliage, cordate, relatively small leaves, well branching and moderately tight, low mounding and trailing plant habit of about medium size.

Description

Latin name of the genus and species of the plant claimed: Sutera cordata.

Varietal denomination: ‘Cay Julav’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Sutera, botanically known as Sutera cordata and hereinafter referred to by the cultivar name ‘Cay Julav’.

‘Cay Julav’ is a product of a planned breeding program. The new cultivar originated from a hybridization made in Andijk, Netherlands, in July 2005.

The female parent was an unpatented, proprietary Sutera plant designated ‘BA04-142-1’, having somewhat larger flowers and lighter lavender flower color, as well as shorter stems than ‘Cay Julav’.

The male parent of ‘Cay Julav’ was an unpatented proprietary Sutera plant designated ‘BA04-8-1’, having purple flower color, less deep green foliage and smaller plant size than ‘Cay Julav’.

The resulting seeds were sown in October 2005, and ‘Cay Julav’ was selected as one flowering plant within the progeny of the stated cross in January 2006 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Cay Julav’ was accomplished when vegetative cuttings were used from the initial selection in the spring of 2006 in a controlled environment in Andijk, Netherlands.

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

‘Cay Julav’ 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.

Plant Breeders' Rights for this cultivar was applied for with the European Union (CPVO) on Jul. 21, 2008. ‘Cay Julav’ has not been made publicly available more than one year prior to the filing of this application.

DESCRIPTION OF DRAWINGS

This new Sutera plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant in full color. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph shows a close-up view of the shoot tips with buds and flowers, and the inset shows a single flower.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Hillscheid, Germany, on mid June 2008 on 17–18 week old plants that were growing (3 each) in 25 cm diameter baskets in a greenhouse at relatively cool conditions. Culture of these plants had started in early February 2008 with planting of rooted cuttings that had been pinched once.

Color chart used: The Royal Horticultural Society Colour Chart (R.H.S.), 2001.

BRIEF SUMMARY OF THE INVENTION

The following observations, measurements, and comparisons describe plants grown indoors and outdoors in Andijk, Netherlands, and in Hillscheid, Germany. 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 Sutera as a new and distinct variety:

• • 1. Large, lavender colored flowers
  • 2. Deep green foliage, relatively small, cordate leaves.
  • 3. Well branched, moderately tight plant habit.
  • 4. Initially mounding, later overhanging and trailing habit of about medium size.

COMPARISON WITH COMMERCIAL CULTIVARS

‘Cay Julav’ differs from the commercial cultivar ‘Taifun Blue’, patented as ‘Wesbavio’, U.S. Plant Pat. No. 14,481, in that ‘Cay Julav’ has larger flowers, lighter lavender flower color and fewer, but thicker stems than ‘Taifun Blue’.

‘Cay Julav’ differs from the commercial cultivar ‘Gulliver Blue Impr.’ (Synonym ‘Glacier Blue Improved’), protected ‘Danova900’, U.S. Plant Pat. No. 17,896, in that ‘Cay Julav’ has a lighter lavender hue of flower color, thicker stems and larger leaves.
