Cryptanthus bromeliads, more 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.
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. But bromeliads are surprisingly tolerant of short periods of drought.
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.
These bromeliads require regulary fertilization for maximum growth and will thrive on any balanced fertilizer: 10-10-10, 14-14-14, etc. But remember to dilute the fertilizer to a 1/4 to 1/2 strength, otherwise, you risk damaging the plant. Feed them every three weeks.
