The hard-leaved haworthias such as Venosa, Attenuata and Limifolia have now been renamed Haworthiopsis by botanists but to fans of these plants, they remain part of this popular group. It's amazing how much abuse these plants can take. Here are some examples of plants that I have salvaged and got growing again just by replanting, watering and putting in a better environment.
This Haworthia Attenuata given as a gift in the tiny little glass bowl and left hanging in a window and not watered for about 5 months. It was completely black and shrivelled and presumed dead when I was given it - I put it in a pot and watered it and less then 24 hours later, it had opened and started showing green in the centre. This is the same plant a few months later.
Likewise, this is a picture of a Haworthia tesselata which had lost all its roots, presumed dead last August and now, a few months later.
While overwatering and bugs can kill these plants, they have an incredible capacity to survive long periods of drought
