16 key plants from the Horniman gardens

Unconventionally contemporary in its planting, the grasslands garden at the Horniman Museum inspires visitors with its continuous colour and life. Words Benjamin William Pope, Photographs Richard Bloom

Where is the Horniman garden?

On a gentle slope in the heart of southeast London, sits a naturalistic display of South African and North American flora, popping with vibrant colour and gently swaying in the soft, warm breeze of late summer. It’s a visual feast and one that feels botanically very different from the surrounding 16 acres of manicured borders and green space, which together make up the gardens of the Horniman Museum.

Inside the Horiman museum

Since opening in 1901, the museum has sought to display, educate and preserve mankind’s cultural response and effect on the natural world, housing everything from textiles to musical instruments, living butterflies and taxidermy. In 2015, when plans for the new World Gallery were taking shape, an opportunity arose to redevelop an aged food garden. The idea was to create a display linking living plants to the new anthropology and natural history exhibitions. Wisely, the museum appointed Sheffield-based professor of horticultural ecology, James Hitchmough, an expert in naturalistic, seed-sown planting schemes and at the forefront of sustainable urban greening.

Given the role of redesigning the space, James explains: “The aim was to create a garden displaying the unique grassland flora of three different regions that have historically been inhabited and utilised by indigenous people, and are now critically endangered.” These include the prairie in North America, along with the Renosterveld steppe and eastern montane grassland in South Africa. While highlighting this plight, the garden also has to work practically, with a long season of interest to entertain visitors and a sustainable focus on its future management and maintenance.

Planting at the Horniman garden

Beginning in early spring with Dodecatheon and Pulsatilla, the flowering continues with Baptisia, Berkheya, species gladioli and much more. Appearing in colourful waves one after the other, the flowering reaches a peak in late summer with grasses, daisies, succulents and perennials jostling for attention. Head gardener Errol Fernandes confirms that the dynamic nature of the planting is key to its success. “Even as the flowers begin to fade late in the year, the garden takes on yet another look,” he says.
