The Flower Dome is the lower but larger of the two, at 1.2 hectares (3.0 acres). It replicates a mild, dry climate and features plants found in the Mediterranean and other semi-arid tropical regions (e.g. parts of Australia, South America, South Africa).
The Flower Dome is 38 metres (125 ft) high and maintains a temperature between 23 °C and 25 °C, slightly lower at night.
The Flower Dome features seven different "gardens" as well as an olive grove with a bistro and a central changing display field has also been incorporated to enable flower shows and displays to be held within the conservatory.
