Ruby Saltbush (Enchylaena tomentosa) is one of the very common bushfoods that are available at this time of year (August at the time of writing). Their small, soft, succulent green leaves and bright red berries are a frequent sight on walks.
While the leaves can be eaten in an emergency, there are better things to chew on. The tiny red berries are salty sweet, quite tasty, though there’s not a lot to them and they contain a seed that you’ll have to spit out.
There are other edible saltbushes listed on the Saltbush page.
