This month Spacehub took a study trip to the Barbican Arts Centre in the City of London to see Nigel Dunnett’s planting scheme in its summer bloom.
Nigel Dunnett, Professor of planting design, urban horticulture and vegetation technology at the University of Sheffield was tasked with redesigning the large podium deck spanning over Beech Street as the existing gardens had become over-mature and costly to maintain.
The new planting scheme was devised to thrive on a thin substrate with minimal maintenance input and be able to survive in UK weather conditions. The planting is made up of three naturalistic mixes, steppe, shrub steppe and light woodland; to respond to the levels of light and shade in the different planter locations. The mix of species gives a changing colour palette and interest throughout the year.
