Bromeliads - Cryptanthus - Are commonly known as earth stars due to rosette-shaped arrangement of the leaves and their low growth habit, are beautiful and incredibly varied plants native to Brazil. There are over 1,200 types of bromeliads within the Cryptanthus genus, with a great variety of foliage. Their colors range from dark green to bright pink to red, and they can be banded, spotted, solid, or virtually any other pattern.
Different Cryptanthus varieties need different levels of light, but most plants within this genus will generally thrive in some sort of indirect sunlight or light shade—remember, they naturally grow under the cover of trees in rainforests. Direct sunlight could potentially bleach the bromeliad’s foliage, or make it appear leathery.
Cryptanthus thrive in tropical conditions, and you should make efforts to keep them moist. Make sure, however, not to rest them in standing water. A moderately damp environment is moisture enough for these plants.
Temperature and Humidity
