The site he chose was the most improbable on Tresco: the ruins of a Benedictine priory founded in 964 AD, on bare granite swept by Atlantic winds that strip nutrients from soil and crystallize salt onto whatever dares to grow. His first act, before the house, was to build a granite wall for shelter. His second was to scatter gorse seeds brought from the mainland because the local gorse grew too low to break the wind. Inside those walls, in soil that has been improved relentlessly for nearly two centuries, the descendants of Augustus Smith now grow Mediterranean palms, South African proteas, Australasian banksias, and South American puyas. The garden holds 2,280 species. Outside the walls, the wind still strips the granite.

Pirates damaged it badly in 1351, and it never recovered from the ...
