An excellent place to spend the day. the exhibitions have three main areas.
The Rainforest Biome - plants fo West Africa, Malaysia and South America all held in the worlds largest conservatory.
Mediterranean Biame - with the sights and scents of the Mediterranean, California and South Africa.
Outdoor Biome with crops that grow in the local climate.
It costs around £14, but if you take public transport you get £4 off.
My favourite was the rainforest - the heat and type of plants was wonderful; also seeing the imitation of Namaqualand South African was great.
