Abstract

A new and distinct Stokesia laevis named ‘MELS BLUE’ is disclosed, characterized by a distinctive spherical plant shape, strong plant stems, and good branching. The new cultivar is a Stokesia typically suited for ornamental container and landscape use.

Description

Latin name of the genus and species: Stokesia laevis.
Variety denomination: ‘MELS BLUE’.
BACKGROUND OF THE INVENTION
The new cultivar is the result of a chance discovery in a commercial nursery in Galder, the Netherlands. The inventor, Adrianus van Heesbeen, a citizen of the Netherlands, discovered the new variety as a single whole plant, mutation of the parent variety, an unpatented, unnamed variety of Stokesia laevis. The discovery was made in July of 2007.
After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘MELS BLUE’ was first performed in the same commercial nursery by vegetative division in March 2008. ‘MELS BLUE’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘MELS BLUE’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘MELS BLUE.’ These characteristics in combination distinguish ‘MELS BLUE’ as a new and distinct Stokesia cultivar:
    • 1. Spherical plant shape.
    • 2. Strong plant stems.
    • 3. Higher quantity of plant stems compared to other Stokesia laevis varieties.
PARENTAL COMPARISON
Plants of the new cultivar ‘MELS BLUE’ are similar to the parent, an unpatented, unnamed variety of Stokesia laevis in most horticultural characteristics. However, ‘MELS BLUE’ differs in having a more round overall plant shape. Additionally, the new variety produces plants that have stronger stems and have more stems than the parent variety.
COMMERCIAL COMPARISON
Plants of the new cultivar ‘MELS BLUE’ are similar to the commercial variety Stokesia laevis ‘Purple Parasols’ U.S. Plant Pat. No. 10,660 in most horticultural characteristics. ‘MELS BLUE’ differs from ‘Purple Parasols’ in overall plant form, having a more even, round plant shape. Plants of ‘MELS BLUE’ have a smaller flower than ‘Purple Parasols’ and more stems, and stronger plant stems than ‘Purple Parasols’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘MELS BLUE’ grown outdoors in Meer, Belgium. This plant is approximately 12 to 18 months old, grown in a 1 liter pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2001, except where general terms of ordinary dictionary significance are used.

The growing temperature ranged from 0° C. to 25° C. at night to 0° C. to 30° C. during the day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Measurements and numerical values represent averages of typical flowering types.
