What is the name of the exotic flower pictured?

The white bat flower (Tacca integrifolia), is a rhizomatous evergreen perennial that is native to rainforests in southeast Asia, India, and southern China. It might look like a normal plant right up until it starts to bloom. Beneath its clusters of purplish flowers hang long, whisker-like bracts that can reach a foot in length. Above the flowers, two widely flared, white bracts (which resemble flower petals) give the plant its "bat wings".

Bat flowers are grown mainly for their blooms, which emerge during the warmest months of the year. Plants typically begin to flower after they have produced at least a pair of full-sized leaves, and they can bloom up to eight times per growing season. The blooms should be left on the plants, as they don't survive long as cut flowers. Bat flowers can be propagated from seeds or by rhizome division. But seeds can take months and are difficult to germinate, so most people opt for division. Separate rhizomes of an established plant in the spring or fall, and either replant them in the ground or a suitable container.
