I was at the recent Gardens Bazaar at HortPark. The Plant Story has taken over the former space occupied by Far East Flora, and is selling lots of terrariums of various sizes in the store. I like this unusually shaped container and bird theme. Perhaps there can be a "Finding Nemo" theme featuring underwater fishes?
By the way, I noticed HortPark is now growing one of my favourite terrestrial orchids Arundina graminifolia (common name: Bamboo Orchid) in the water of the Water Garden. This shows that it is actually possible to grow some terrestrial plants in water, just like what Khoo Teck Puat Hospital is doing in their pond.
