I may have seen the Grevillea robusta (common name: Australian Silky Oak; Family: Proteaceae) at Bougainvillea Park when I was managing it many years ago and planted it and other cultivars of it at HortPark, but this was the first time I actually see a flowering one at Pasir Ris Park. How interesting!
