Phlox x arendsii 'Hesperis' is a hybrid phlox in the Polemoniaceae that offers sustained summer flowering. It is grown for its season-long display from June to September. Plants form multi-stemmed clumps that produce compact flower heads over several weeks. Regular 

 and occasional division keep plants productive.

Phlox x arendsii 'Hesperis' sits within the genus Phlox and the family Polemoniaceae and is one of the garden hybrids selected for extended summer bloom. As a cultivated phlox, it is valued for providing colour through the summer months and fits into perennial planting schemes where continued flowering is needed. Its flowering season runs from June to September. Choose a site with reasonable air movement to reduce foliage diseases, and avoid prolonged waterlogging at the roots. Remove spent flower stems during the season to encourage further bloom and tidy the plant for neighbour planting. Established clumps benefit from lifting and dividing when they become congested; this refreshes vigour and can be done outside frosty conditions. Short stems can be cut for vase work while the plant is in full flower, and dividing also offers a straightforward propagation route. Where space allows, plant 'Hesperis' among later-flowering perennials to extend the border sequence; it also works well in mixed-cottage and formal beds where a steady summer display is required. Expect reliable flowering from June to September, making this cultivar a practical choice for summer borders and cutting gardens.
