Summer is the season when gardens truly come to life, bursting with colours, textures, and blooms that turn outdoor spaces into a haven of beauty. To achieve a garden that shines all summer long, adding vibrant perennials is a must. These long-lasting plants return year after year, providing structure and effortless charm. Today, we’re spotlighting five spectacular summer perennials—Acanthus Spinosus, Agapanthus Africanus, Astrantia Hadspen’s Blood, Campanula Pink Octopus, and Coreopsis Zagreb.
These plants not only thrive in UK gardens but also create stunning displays that brighten borders, attract pollinators, and elevate your garden’s design.
1. Acanthus Spinosus: The Architectural Marvel
Known as Bear’s Breeches, Acanthus Spinosus is a striking perennial prized for its bold, architectural foliage and tall flower spikes. Its spiny-edged, glossy green leaves provide an impressive backdrop to towering spikes of pale pink and purple flowers that bloom in summer. This plant is ideal for creating a dramatic focal point in your garden.
Acanthus thrives in well-drained soil and partial shade, although it can tolerate full sun in cooler regions. Its hardy nature ensures it performs well in UK gardens, and its drought tolerance makes it a great choice for low-maintenance gardening.
2. Agapanthus africanus: Exotic Elegance
For a touch of Mediterranean charm, Agapanthus Africanus, or African Lily, is a showstopper. This clump-forming perennial produces striking blue, trumpet-shaped flowers on tall, slender stems. The blooms appear in late summer, creating a spectacular display that catches the eye and draws pollinators like bees and butterflies.
Agapanthus prefers full sun and thrives in well-drained soil, making it a fantastic addition to borders or patio containers. In frost-prone areas, it’s worth planting it in pots that can be moved to a sheltered spot in winter.
3. Astrantia ‘Hadspen’s Blood’: A Deep Red Delight
If you’re searching for a perennial with rich, jewel-toned blooms, look no further than Astrantia ‘Hadspen’s Blood.’ This variety of Masterwort features deep burgundy-red flowers that create a striking contrast against lush green foliage. Its long-lasting blooms are perfect for cutting, making it a favourite among florists and gardeners alike.
Astrantia thrives in partial shade, making it ideal for woodland gardens or shady borders. It also performs well in moist, fertile soil, and its nectar-rich flowers are a magnet for pollinators, adding ecological value to its beauty.
4. Campanula ‘Pink Octopus’: A Quirky Bloomer
Add a touch of whimsy to your garden with Campanula ‘Pink Octopus.’ This unique bellflower variety features slender, pink, tentacle-like petals that give it a strikingly unusual appearance. Its soft, delicate foliage provides an attractive backdrop, while its compact growth habit makes it a fantastic choice for borders or containers.
Campanula prefers well-drained soil and full sun to partial shade. Its long flowering period, from early summer through to autumn, ensures your garden stays vibrant for months.
5. Coreopsis ‘Zagreb’: A Burst of Sunshine
Bring a splash of golden sunshine to your garden with Coreopsis ‘Zagreb.’ This cheerful perennial produces masses of bright yellow, daisy-like flowers on delicate, fern-like foliage. It blooms profusely throughout the summer, creating a lively display that brightens any garden space.
Coreopsis is incredibly easy to care for, thriving in full sun and well-drained soil. Its compact size makes it perfect for edging borders, filling gaps, or planting in containers. It’s also a favourite among pollinators, adding vibrancy and ecological benefits to your garden.
Designing a Stunning Summer Border
To create a harmonious and vibrant summer display, combine these perennials in a layered border design:
- Background layer: Plant the tall, bold spikes of Acanthus Spinosus and Agapanthus Africanus for dramatic height.
- Middle layer: Add the jewel-toned blooms of Astrantia Hadspen’s Blood to bring depth and a pop of rich colour.
- Front layer: Use the quirky, pink blooms of Campanula Pink Octopus alongside the golden flowers of Coreopsis Zagreb to create a cheerful foreground.
This combination ensures a balance of height, colour, and texture, while also supporting pollinators and enhancing the biodiversity of your garden.
Caring for Your Summer Perennials
While these perennials are relatively low-maintenance, they’ll thrive with a bit of care:
- Watering: Regular watering during dry spells, especially when plants are establishing, will help them thrive.
- Feeding: A general-purpose fertiliser applied in spring will encourage healthy growth and blooming.
- Pruning: Deadhead spent flowers to prolong the blooming period and cut back foliage in late autumn for a tidy appearance.
