There are 2 Domes - the Flower Dome & the Cloud Dome - the Flower Dome is home to all sorts of plants from cacti, succulents, trees, flowers etc etc. It's all air-conditioned too - they have their own eco-system going so it's entirely self-sufficient.
They have different themed displays - this one was finishing - Nursery Rhymes - it was finished & a new one was being done.
Lupins - HofM informed me.
Amazing sculptures everywhere.
Ancient olive trees that must have been brought in & replanted - can you see why it took us so long to look around.
