Ginger produces clusters of white and pink flower buds that bloom into yellow flowers. Traditionally, the rhizome is gathered when the stalk withers; it is immediately scalded, or washed and scraped, to kill it and prevent sprouting. The fragrant perisperm of the Zingiberaceae is used as sweetmeats by Bantu, and also as a condiment and sialagogue. Ginger produces a hot, fragrant kitchen spice. Ginger can be used to make into candy or ginger wine.
