Ice Plants (Mesembryanthemum species) are a beautiful family of succulent, usually coastal, groundcovers that thrive in saline environments.
They get their names from the glistening, water laden cells on their leaves and stems.
Ice Plants live in saline environments and deal with the high levels of salt by pumping it into external cells so that, when these cells are ruptured, the salt is released back into their environment.
Most Ice Plants are quite tasty, though, as their preferred environment suggests, they can be a little salty for some tastes.
A little safety note. Eating lots of salty plants such as Saltbushes, Ice Plants and Samphires can give you an upset stomach and diarrhoea from the salt contained in them. Moderation in all things.
