At Boma, we stock an ever-changing collection of herbaceous perennials, bedding plants, and shrubs arriving weekly throughout late spring, early summer, and beyond. Our team carefully curates species that thrive in urban London gardens, ensuring strong growth and lasting colour from mid-summer into late autumn.

Our hardy perennial range includes blue flowers like Agapanthus and Nepeta ‘Walker’s Low’, and yellow flowers such as Coreopsis and Rudbeckia, each offering good ground cover and season-long interest. For a touch of drama, try Giant Hyssop (Agastache)—a deer-resistant favourite that adds height, fragrance, and structure to borders.

Many of our favourites also hold the RHS Award of Garden Merit, recognised for their reliability, garden merit, and exceptional performance across full sun and partial shade conditions.

Popular Summer Perennial Flowers and Bedding Plants

We’re proud to offer perennials and annual bedding flowers perfect for every garden style:

• Perennial flowers such as Lavandula, Astrantia, and Salvia ‘Caradonna’ deliver flowers from early summer through late autumn.
• Bedding plants like Begonia, Lobelia, and Petunia produce brightly coloured blooms that flourish summer long, ideal for baskets or window boxes.
• Flowering shrubs including Hebe, Philadelphus, and Weigela add texture and contrast to mixed borders.

All our selections are cultivated to grow perennials successfully in both full sun and partial shade, with many thriving in well-drained soil to reduce maintenance effort while enhancing curb appeal.
