Cryptanthus
Meet the Cryptanthus
Cryptanthus, commonly known as "Earth Stars," are unique and attractive bromeliads native to Brazil. They have rosette-shaped leaves that come in various colors and patterns, making them popular in ornamental plant collections. These plants are relatively small, typically growing to about 6-12 inches in diameter, and are well-suited for terrariums or as indoor houseplants. They prefer bright, indirect light and well-draining soil, and they’re quite hardy, making them a great choice for both novice and experienced plant enthusiasts.
Light
Grow Cryptanthus in a bright spot. These small indoor plants can take some direct sun on their leaves, so they're perfect for dressing up an otherwise bland window sill. As a general rule, the brighter the light, the more colorful the plants are.
Pet Friendly

Water
Water Cryptanthus so the soil just dries before watering again. They don't seem to be particularly fussy and will thrive in moist soil. Likewise, if you forget to water your Cryptanthus now and again, they don't mind.
Humidity
Cryptanthus plants thrive in high humidity, ideally between 50% and 70%. To maintain this, consider placing the plant on a humidity tray or using a humidifier, and avoid letting it dry out completely.
Temperature
It prefers temperatures between 60° and 85° F.

Common Problems Q&A
Why are my leaves yellowing?
This is generally a sign that you are overwatering your plant. This may also be a sign your plant is getting too little light. Try moving your plant to an area where it will receive bright, indirect light.
Why are my leaves curled and brown?
Your Cryptanthus is getting too little water and too much light. Cryptanthus plants do best in bright, indirect light.
Why is mold developing on the soil?
This is a sign your plant is receiving too little light, and is being over watered. Although this is harmless, it may be unsightly and may want to remove it. Remove the top two inches of soil and replace it with fresh soil.
