Haworthias make excellent plants for an open terrarium as they are slow growing and require very little watering. What's more, they come in a huge variety of shapes and colours and make a great focal point for a terrarium display. Good varieties to choose include Haworthia fasciata, which has zebra-like dark green leaves with white stripes, Haworthia tessellata, which has triangular leaves with square patterning, and Haworthia trunacata, which has unusually shaped leaves in rows. Position your terrarium near a window where it will receive bright but indirect light, and your haworthias will thrive.
