Haworthia Attenuata (or H. Fasciata) a.k.a the Zebra Plant

Haworthia Attenuata pictured above in a Living Coaster.

The Look: Resembles a tiny aloe plant. With fleshy green pointed leaves and white bumpy stripes. With low light, the leaves tend to get a little wild in search of sunlight. I've had some that resemble the tentacles of an octopus or squid. With bright light, the leaves will stay small and more orderly. 

Daily Care: Plant in quick draining cactus soil. Water frequently in spring summer months, the soil does not have to dry completely between waterings at this time, just make sure it’s not sitting in excess water. Fertilize with diluted liquid cactus fertilizer once a month during the spring/summer, never during the winter. The zebra plant likes indirect full sun to bright shade but will tolerate full shade for a while. If the leaves turn white or light yellow, it is getting too much direct sun. This plant does well on an indoor window sill or as an office plant if you give it some weekend sun.

Flowers: Not common for indoor plants, but it can produce small pink or white flowers at the end of an inflorescence (thin stem). 

Propagation: once mature, offshoots will emerge from the bottom of the plant. These offshoots can be removed with a knife, left to callus over, then replanted. 

Growth: Slow growing, especially during the winter. You will probably need to re-pot after 2 or more years. To keep it small, you can also trim off the bottom leaves if they spread out too far to fit easily in the coaster. 

Living Coaster Compatibility: Excellent. If planted at a young age (small size), this small and slow growing plant thrives in a Living Coaster. This plant prefers not to have water on inside the rosette, so watering it from below like in a coaster is ideal. It is quite hardy and can tolerate frequent waterings in the spring/summer and as little as 1-2 waterings in the winter time. It can also handle temperatures down to near freezing.
