A classic and beautiful succulent, the Zebra Cactus is one of the most popular Haworthia varieties, and for good reason. Their skinny green leaves are marked with bright white stripes, providing a ton of contrast and succulent happiness to your windowsill.

These hardy dudes can live for a long time in a south or west facing window, provided they get plenty of sun during the day. Water when the soil is completely dry - overwatering is the most common cause of death. Avoid their leaves when watering.
