These plants belong to bromeliads but do need a different care than epiphyte bromeliads.
Cryptanthus does grow on ground and have more developed root system. You can keep the soil slightly moist at summer time but do not overwater. At wintertime, it´s better to let the soil dry out before watering.
Cryptanthus plants need only indirect light as too much direct hot sun will bleach the leaves.
They do like high humidity so you can spray them a little every now and then.
