Torch ginger

I spotted this spectacular torch ginger flower in the hothouse at the Wintergarden in the Auckland Domain.

From Wikipedia:

"The showy pink flowers are used in decorative arrangements while the flower buds are an important ingredient in the Nonya dish laksa. In North Sumatra, the flower buds are used for a dish called arsik ikan mas (Andaliman/Szechuan pepper Spiced Carp)".
