Geranium plant named ‘Dark Roast’

A new cultivar of Geranium maculatum plant named ‘Dark Roast’ that is characterized by its flowers that are vibrant fuchsia in color with white throats, its green-burgundy-bronze colored foliage that persists through the summer and into fall with consistent moisture, its palmate-shaped leaves, and its blooming period due to high heat tolerance.

1. 11. A new and distinct cultivar of Geranium plant named ‘Dark Roast’ as herein illustrated and described.

Botanical classification: Geranium maculatum. 
Cultivar designation: ‘Dark Roast’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Geranium maculatum ‘Dark Roast’ and will be referred to hereafter by its cultivar name, ‘Dark Roast’. ‘Dark Roast’ is a new cultivar of herbaceous perennial grown for use as a garden plant.
‘Dark Roast’ was discovered by the Inventor as a chance seedling in a garden plot in Landenberg, Pennsylvania in May of 2017. The exact parentage is unknown, however it is most likely a seedling of open pollinated ‘Espresso’ (not patented) based on its characteristics and its proximity to the new cultivar as the new cultivar was found growing in garden plot of ‘Espresso’.
Asexual propagation of the new cultivar was first accomplished by division under the direction of the Inventor in Landenberg, Pennsylvania in April of 2021. Asexual propagation by division and tissue culture tissue using meristematic tissue has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of ‘Dark Roast’. These attributes in combination distinguish ‘Dark Roast’ as a new and distinct cultivar of Geranium. 

    
    
        1. ‘Dark Roast’ exhibits flowers that are vibrant fuchsia in color with white throats.
        2. ‘Dark Roast’ exhibits green-burgundy-bronze colored foliage that persists through the summer and into fall with consistent moisture.
        3. ‘Dark Roast’ exhibits palmate-shaped leaves.
        4. ‘Dark Roast’ exhibits a long blooming period due to high heat tolerance.
    
    


The probable parent plant differs from ‘Dark Roast’ in having lighter bronze colored foliage that does not last as long in the season, lighter colored flowers and lower heat tolerance. ‘Dark Roast’ can be most closely compared to the Geranium cultivars ‘Huggy Bear’ (U.S. Plant Pat. No. 36,258) and ‘Elizabeth Ann’ (U.S. Plant Pat. No. 11,252). ‘Huggy Bear’ is similar to ‘Dark Roast’ in having dark green-burgundy-bronze foliage and a long blooming period. ‘Huggy Bear’ differs from ‘Dark Roast’ in having flowers that are lighter and less vibrant in color, a less floriferous blooming habit, and foliage that is lighter in color. ‘Elizabeth Ann’ is similar to ‘Dark Roast’ in having dark colored foliage, and a similar blooming period. ‘Elizabeth Ann’ differs from ‘Dark Roast’ in having flowers that are light pink in color and darker colored foliage.
