About This Business

Sienna Blake is a Bristol-based landscape designer specialising in ecologically sensitive garden design. A graduate of the Royal Botanic Gardens Kew diploma, Sienna creates spaces that work with local ecology rather than against it — prioritising native planting, natural drainage, and zero-peat growing media. Her residential portfolio spans urban courtyard gardens to multi-acre country estates, and she leads a community kitchen-garden programme across three Bristol schools.

Growing Greener: Sienna Blake's Sustainable Design Vision

By the Lumatic Editorial Team · March 25, 2024

There is a radicalism lurking beneath Sienna Blake's quietly confident manner. She will not touch peat. She refuses commissions that require the removal of mature trees. She insists on a biodiversity audit before putting pencil to paper. 'A garden that harms its environment is not a garden,' she says. 'It's a liability.' Since establishing her practice in Bristol in 2017, Sienna has completed more than a hundred projects, from a tiny backyard rewilding in Montpelier to a four-acre estate garden in the Mendips. Her design vocabulary — meadow grass, native hedgerow, rain garden, permeable paving — is consistent across all scales, adapted to each site's specific soils, aspect, and ecology. The school kitchen-garden programme, now in its third year, has introduced over 400 children to growing food. 'If you want to change how people relate to the natural world, you have to start young,' Sienna observes.
