Cryptanthus spp.

Common names

Earth Star, Starfish Plant

Description

Cryptanthus is a stunning genus of bromeliads that earns its nickname, "Earth Star," for its rosette shape and star-like appearance. These compact plants are adored for their vibrant, patterned foliage, which comes in a range of colors, including pink, red, green, and silver, often with striking stripes or mottling. While they rarely flower, the foliage is the true showstopper, making them perfect for brightening up small spaces, terrariums, or mixed plant displays. They are easy to care for, thrive in a variety of indoor and outdoor settings, and are a must-have for anyone who loves unique foliage.

Light requirements

Earth Stars prefer bright, indirect light to bring out their vivid colors and patterns. They can tolerate some direct morning sun but avoid harsh afternoon sunlight, which may scorch their leaves. In lower light, the colors may become less vibrant.

Soil preferences, including pH and drainage

Cryptanthus thrives in well-draining, slightly acidic soil with a pH between 5.5 and 6.5. A bromeliad mix or a combination of regular potting soil and sand or perlite works well. These plants are terrestrial bromeliads, so they don’t need the epiphytic setup that many other bromeliads require.

Water needs

Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry, and ensure proper drainage to prevent root rot. Unlike some bromeliads, Cryptanthus doesn’t require a water reservoir in its rosette. Mist the plant occasionally to maintain humidity, especially in drier indoor environments.
