Gasteria bicolor var. bicolor (Haworth): A fun, easy houseplant, even for beginners. Its foliage is marbled green with bronze flushes when grown in direct sun. This is a somewhat variable species, but it can grow large over the course of many years with leaves and stems up to 8.0" long.
Gasteria have low light and water requirements. They are one of the best types of succulents to grow indoors because they can tolerate low light conditions and still maintain their form and colors. Plant Gasteria in deep pots with drainage holes as they grow deep roots and will not tolerate standing water. Use a gritty, well-draining soil and water deeply, but only when the soil is fully dry. Protect from frost.
