Haworthia attenuata (Zebra plant, Window plant)

Related to aloes and agaves, this tiny succulent produces peculiar white bands on the undersides of its leaves. These are commonly grown in windowsills due to their peculiar appearance, their tolerance of neglect, and their ability to tolerate part-shade, something very rare among succulents. Zebra plants grow slowly, and they can live up to 50 years old.
