Strawberry begonia ( Saxifraga stolonifera) plants make a great addition to open or closed terrariums. They require regular watering and do best when the soil is evenly moist and can tolerate average to high humidity. Their textured leaves, colorful petioles, and interesting growth habit add visual interest to any terrarium setup. They grow 6 to 18 inches tall and 12 to 24 inches wide, so a medium to large terrarium is best. The roots of begonias may be toxic to some animals.
