Solenostemon plant named ‘Mos Rosbast’

Abstract

A new Solenostemon plant named ‘Mos Rosbast’ particularly distinguished by the bold slightly mottled red hues in the center of the foliage, with greyed-purple borders and yellow-green margins, with an upright, well branched and uniform plant habit.

Description

Latin name of the genus and species of the plant claimed: Solenostemon scutellarioides.

Varietal denomination: ‘Mos Rosbast’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Solenostemon, botanically known as Solenostemon scutellarioides, and hereinafter referred to by the variety name ‘Mos Rosbast’.

‘Mos Rosbast’ is a product of a planned breeding program. The new cultivar has bold slightly mottled red hues in the center of the foliage with greyed-purple borders and yellow-green margins, with an upright, well branched and uniform plant habit.

‘Mos Rosbast’ originated from a hybridization made in January 2006 in a controlled breeding environment in Andijk, Netherlands. The female parent was the unpatented proprietary plant designated ‘CS06-29-1’ with less intense foliage color, larger foliage size and thinner stems.

The male parent of ‘Mos Rosbast’ was an unpatented proprietary plant identified as ‘CS06-1-1’ with less rose color in the foliage, smaller foliage size, and has less of a crenate margin. The resultant seed was sown in July 2006.

‘Mos Rosbast’ was selected as one flowering plant within the progeny of the stated cross in September 2006 in a controlled environment in Andijk, Netherlands.

The first act of asexual reproduction of ‘Mos Rosbast’ was accomplished when vegetative cuttings were propagated from the initial selection in September 2006 in a controlled environment in Andijk, Netherlands.

BRIEF SUMMARY OF INVENTION

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

‘Mos Rosbast’ 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 Feb. 18, 2010 (#10-6844). ‘Mos Rosbast’ 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 Solenostemon as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical foliage characteristics of ‘Mos Rosbast’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a potted plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs were taken in mid-June 2010 in Andijk, Netherlands. These plants were about 12 weeks old grown in a greenhouse in a bench trial in 4 inch pots.
