Phlox × arendsii 'Hilda'

About

Phlox × arendsii 'Hilda' is a cultivated Phlox in the Polemoniaceae family that provides a summer display, flowering from June to September. It is grown for its season-long blooms and is used where a sustained floral display is wanted. Plants benefit from airflow between clumps and removal of spent flowers to extend the display. A regular feed during the season supports continued flowering.

About the genus

Phlox is a genus of 68 species of perennial and annual plants in the family Polemoniaceae. They are found mostly in North America in diverse habitats from alpine tundra to open woodland and prairie. Some flower in spring, others in summer and fall.

In the garden

Phlox × arendsii 'Hilda' sits within the genus Phlox and the Polemoniaceae family and is selected for its summer flowering habit, with blooms occurring from June to September. In a temperate UK garden it performs best when treated as a summer-flowering perennial, supplying colour through the main months of the season. Position plants where they have room for air movement between crowns and where you can access them for routine maintenance. Aim for a free-draining, fertile planting site and keep soil reliably moist through the active growing season; erratic moisture can stress plants during bloom. Apply a balanced liquid feed or a low-nitrogen granular feed in spring and again in mid-summer to support repeat flowering. Space specimens to avoid overcrowding and reduce the risk of foliar disease, and remove spent flower heads to encourage further bloom. Phlox × arendsii 'Hilda' suits mixed herbaceous borders and perennial beds where summer colour is required, and it pairs well with taller grasses or later-flowering perennials that provide structural support. Given its extended flowering from June to September, regular deadheading will noticeably prolong the season of interest.
