Plant Family: Liliaceae
Common Name: Zebra haworthia
General Description
Comprising about 70 species of small, succulent, cold-tender perennials, this southern African genus contains many excellent subjects for containers or frost-free gardens. Most cultivated haworthias come from desert or semi-desert regions of South Africa that receive little or no summer rainfall.
Most Haworthia species form ground-hugging or short-stemmed rosettes of fleshy, somewhat triangular, firm- or soft-textured leaves. The leaves of several species (including H. cymbiformis) have a mosaic of translucent "windows" at their tips, which admit light to an interior layer of photosynthesizing cells. Warty silver-gray tubercules mark the leaves of some species (such as H. attenuata), giving them an almost reptilian appearance. Still others (H. arachnoidea, for example) produce spherical rosettes covered with a cobweb of fine white bristles. Among the most striking and sought-after haworthias are H. truncata and its allies, whose "sawed-off" leaves resemble miniature stone columns.
Many haworthias multiply rapidly into sizable clumps when grown in optimal conditions. Most have fleshy roots, but a few are tuberous-rooted.
Haworthias are not showy bloomers, producing small, pale, tubular flowers on tall, thin, wiry stems. Blooming season differs among species. Plants sometimes set seed, which if sown may result in hybrid seedlings. Many formerly supposed species of Haworthia are now known to be hybrids.
These succulents do best in porous soil and bright filtered light. Water sparingly in summer and winter, and more frequently in spring and fall. Haworthias take very well to container culture and are splendid in decorative pots. Drought and sun may cause reddening of the leaves. Plants are easily propagated by separation of rosettes.

Strikingly well written blog!!
I have a question. I had one that was over 6" growing over 14 babies this last fall. She was doing great and the babies were growing so fast. I had her for 2 years, in that time I learned how to water her properly and what soil she needed....by making mistakes. I checked on her a few weeks ago and she started turning a translucent green, and mushy...kind of like jelly. It started from the base/bottom all the way to the top. I cut the bad parts away little by little and it didnt help. She and her babies ar all gone, they each fell apart and seemed to be what was rot. There isnt any mold or bugs. I was wondering if anyone might have an answer to what may have happened? I loved that plant and have many more but that one was given to me by a dear friend.
In some time, cacti doesn't need water or wants only few water. It's the cacti nature to rest and stop growing : dormancy. It's usually in winter. From your information, I think it's difficult to help your cacti survive. Cutting little by little is not the good way to do. If your plant is still alive, cut the above part of the rotten part away and keep the cacti dry for 1-2 weeks. Later, try to pot it. I have done it before but if it's too late, don't be too sorry. I think your friend will understand you as it's natural and possible that cacti will be rotten easily.
I divide the babies from the "mother" at least once every two years. But I have one that's been in the kitchen window for probably 10 years now. Just water it about once a month.. Also, I mixed the "succulent soil" with a little bit of sand to help keep the soil dry too. I used the succulent and cacti soil from miracle gro.
