Late Summer Blooms: Best Flowering Plants for UK Gardens in August

As the sun-kissed days of summer continue to grace our landscapes, the gardens across the United Kingdom burst forth in a colourful symphony of late summer blooms. August is a time when the diligent gardener is rewarded with a palette of vibrant hues and intoxicating fragrances. If you’re wondering which flowering plants to embrace for a spectacular August garden, look no further. We’ve curated a list of the best flowering plants that thrive in the UK climate during this season, along with insights into their care, ideal planting locations, and maintenance tips to ensure prolonged blooming.

Lavender (Lavandula angustifolia)

A quintessential English garden plant, lavender’s soothing aroma and delicate purple flowers make it a standout. Plant it in well-draining soil and a sunny spot. Regular pruning of spent flowers can encourage a second wave of blooms.

Helenium (Helenium autumnale)

With its warm shades of red, orange, and yellow, Helenium adds a touch of fiery brilliance to late summer beds. These hardy perennials love full sun and moderately fertile soil. Deadhead blooms to prolong flowering.

Rudbekia (Rudbeckia hirta)

Commonly known as Black-Eyed Susan, Rudbeckia’s golden-yellow petals and distinctive dark centers bring cheer to any garden. These sun-loving plants thrive in well-draining soil and require minimal care for continuous flowering.

Cosmos (Cosmos bipinnatus)

Graceful and dainty, cosmos blooms in various shades, from pinks to whites. These annuals prefer a sunny spot with well-draining soil. Regular deadheading not only encourages new blooms but also adds to the plant’s overall tidiness.

Agapanthus (Agapanthus africanus)

Agapanthus, or Lily of the Nile, boasts striking clusters of blue or white flowers atop tall stalks. These perennial plants prefer full sun to partial shade and thrive in containers or in well-draining garden soil.

Dahlia (Dahlia spp.)

Renowned for their diversity in colours, shapes, and sizes, dahlias are a late summer favourite. These tuberous perennials prefer a sunny location with fertile, well-draining soil. Regular deadheading and disbudding can lead to a prolific display of blooms.

To ensure the longevity and vibrancy of your late summer garden, there are a few essential care tips to consider:

Watering: while August can bring intermittent rain, be sure to water your plants adequately during dry spells. Water at the base of the plants to minimize moisture on the foliage, reducing the risk of diseases.

Mulching: apply a layer of organic mulch around your plants to conserve soil moisture, suppress weeds, and regulate soil temperature.

Fertilizing: if your plants show signs of nutrient deficiency, consider a balanced, slow-release fertilizer to provide them with the necessary nutrients for continuous blooming.

Deadheading: regularly removing spent blooms prevents plants from channeling energy into seed production, encouraging them to produce more flowers instead.

Pest and Disease Management: keep a vigilant eye out for pests and diseases that might appear during late summer. Early detection and intervention are key to maintaining a healthy garden.
