After breakfast we visit the Singapore Botanic Gardens for further exploration. We will have a presentation on the Singapore Cities’ Sustainability Index, a unique and important idea by Dr Lena Chan, Group Director of the National Biodiversity Centre, in which science and sustainability are considered together. We will also look at the extraordinary ‘orchid story’. Since 1928 the gardens has been developing orchid hybrids and this work kick-started a now nationally important industry. We will look at the process and separately, the product, one of the world’s great collections. Later we travel to Hort Park to visit this 9 hectare site which is a training and education facility for Singapore gardeners. It has a range of specialised gardens, sales facilities, and educational tours. It is in our view the model of ‘garden education’! Late afternoon, evening free.
