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.
