Description
BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sutera known botanically as Sutera and referred to hereinafter by the cultivar name ‘Yasflos’. It is a cross between two parent seedlings, both Sutera cordata (not patented). The seed parent is Sutera cordata (not patented) and the pollen parent is Sutera cordata (not patented). The new Sutera was selected from a long term breeding program designed to produce new patio plants and hanging baskets. The inventor conducted the first crosses in a cultivated area of Congleton, Chesire England in 1998. ‘Yasflos’ was selected by the inventor in 1998 as a container plant suitable for temperate climates.

‘Yasflos’ was selected for the specific traits of vigorous growth, free-flowering, bushy cascading habit and numerous large bluish flowers. The combined characteristics of the new invention ‘Yasflos’ are unique and make ‘Yasflos’ a distinct hanging basket Sutera, setting it apart from all other existing varieties known to the inventor. The closest comparison variety is Sutera ‘Lavender Showers’ (unpatented). In comparison ‘Yasflos’ exhibits larger, more abundant flowers that are darker in color with more blue than those of ‘Lavender Showers’ (unpatented).

The first asexual propagation was conducted by the inventor in the summer of 1998 in a cultivated area of Congleton, Chesire, United Kingdom, using cuttings. In vegetative propagation, ‘Yasflos’ has remained true to type and been found stable in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. ‘Yasflos’ is selected as a new basket Sutera, for its vigorous and rapid growth, free-flowering, bushy cascading habit and numerous large blue flowers. Compared to Sutera ‘Lavender Showers’ (unpatented), the flowers of ‘Yasflos’ are larger, more abundant and darker in color with more blue than lavender. These attributes in combination distinguish this cultivar from all other existing varieties known to the inventor.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance of the new cultivar.

The photo on sheet 1 is a good depiction of the entire plant showing foliage, flower presentation, color and plant habit.

The upper photo on sheet 2 is a close-up of the ‘Yasflos’ flower.

The lower photo on sheet 2 compares ‘Lavender Showers’ (unpatented) on the left to the foliage and flowers of ‘Yasflos’ on the right. All photographs are taken of plants grown in one-gallon containers. The prints are made using conventional photographic techniques and although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new cultivar as grown in a one-gallon container under greenhouse conditions in Encinitas Calif. Phenotypic differences may be observed with variations in environmental, climatic and cultural conditions. The color determinations are in accordance with The Royal Horticultural Society Colour Chart, except where general color terms of ordinary dictionary significance are used.
