Title of Invention: Phlox plant named ‘Grenadine Dream’
Abstract: A new and distinct cultivar of Phlox plant named ‘Grenadine Dream’, characterized by its upright and relatively compact plant habit; freely flowering habit; red purple-colored flowers; relative resistance to Powdery Mildew; and good garden performance.
Detailed Description: Part general_description_paragraphs: Botanical designation: Phlox paniculata. 
Cultivar denomination: ‘Grenadine Dream’.
Part BACKGROUND OF THE INVENTION: The present invention relates to a new and distinct cultivar of Phlox, botanically known as Phlox paniculata and hereinafter referred to by the name ‘Grenadine Dream’.
The new Phlox is a product of a planned breeding program conducted by the Inventor in Haarlem, The Netherlands. The objective of the breeding program was to create new compact Phlox cultivars with attractive flower coloration and Powdery Mildew resistance.
The new Phlox originated from a cross-pollination made by the Inventor in 2004 in Haarlem, The Netherlands, of two unidentified selections of Phlox paniculata, not patented. The new Phlox was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Haarlem, The Netherlands in 2005.
Asexual reproduction of the new Phlox by cuttings in a controlled environment in Haarlem, The Netherlands since 2005, has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.
Part SUMMARY OF THE INVENTION: The cultivar Grenadine Dream has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultivar practices such as temperature 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 ‘Grenadine Dream’. These characteristics in combination distinguish ‘Grenadine Dream’ as a new and distinct cultivar of Phlox: 

    
    
        1. Upright and relatively compact plant habit.
        2. Freely flowering habit.
        3. Red purple-colored flowers.
        4. Relatively resistant to Powdery Mildew.
        5. Good garden performance.
    
    


Plants of the new Phlox and the parent selections differ primarily in flower coloration and plant height.
Plants of the new Phlox can be compared to plants of the cultivar Red Riding Hood, not patented. In side-by-side comparisons conducted in Haarlem, The Netherlands, plants of the new Phlox and the cultivar Red Riding Hood differed in the following characteristics:

    
    
        1. Plants of the new Phlox were more compact than plants of the cultivar Red Riding Hood.
        2. Plants of the new Phlox wee sturdier and had thicker stems than plants of the cultivar Red Riding Hood.
        3. Plants of the new Phlox had darker green-colored and healthier leaves than plants of the cultivar Red Riding Hood.
        4. Plants of the new Phlox had darker-colored flowers than plants of the cultivar Red Riding Hood.
