Josephine do you mean the current one? the pitcher plant? I have changed them around in the last couple of hours.
The red one was one of my favourite plants, Sturt's Desert Pea. Stunning but painful to grow.
This is a hybrid of Nepenthes maxima x N. alata. None of these are Australian species. However, three species of carnivorous nepenthes occur in Australia, two of which are endemic.
This was the pea.
