In evolutionary terms the bromeliad is a relatively recent family of plants. Because of the types of climate they favour they usually have a poorly developed root system. Consequently many have evolved a tight structure at the base of their leaves that traps water and nutrients. If the indoor gardener knows anything about bromeliads it is that they should be watered in the centre of the plant. This is also the point from which the spectacular flowers grow.
