Daiv of Cactiguide helped me identify this plant.
Aechmea fasciata is also known as the silver vase bromeliad. It is an epiphytic bromeliad which is native to Brazil. It has vase-shaped rosettes of silver-green leaves. It is about 2 ft tall, has silver-green leaves and an inflorescence made of pink bracts and tiny blue and red flowers. ( Almost looks like the matchstick flower that I saw at Mysore). This plant is commonly grown indoors.
