Flower Dome

This guide to the Flower Dome at Gardens by the Bay explains a contradiction: keeping a greenhouse cool in one of the hottest, most humid cities on earth. It follows architects WilkinsonEyre's decision in two thousand and six to reject an air-conditioned glass box, and the engineering that lets the Supertrees next door share the cooling work instead. You'll hear about the mix of plants sheltered inside, from ancient olive groves to South African proteas. Look for the seasonal Flower Field at the centre, which changes several times a year.
