I was at the KTPH for my dental appointment and the landscape has matured quite a bit since I last saw it. In terms of plant selection, there are good and not so good choices too.At the far end near the Yishun Pond was a transplanted Enterolobium cyclocarpum (common name: Elephant Ear Tree; Family: Fabaceae/Leguminosae). From what I saw of the site conditions from the other side, it was definitely not planted at the best location since its tree collar was buried at least a foot deep and there is no space for its extensive surface roots to grow.
A link on this huge interesting tree is shown below:
