These are the Calathea 'Silver Plate' plants at the Silver Garden.

Compared to some Calathea, they seemed more hardy than others in that they can take slightly dry conditions without their leaves curling up. Only when the weather is extremely hot and when they are exposed to full sun do they show signs of water stress. The upperside of the leaves is completely white or silver whilst their underside is purple. I guess the white does help to reflect off some of the light and heat? They are best planted in semi-shade conditions with indirect sunlight so that there is sufficient light to induce flower production.

The colourful pink bracts that subtend the small flowers resemble that of the Calathea loeseneri that is far more sensitive to water stress.
