Fleshy-stalk pelargonium is a drought-deciduous succulent native to South Africa and Namibia. How fleshy is the stalk? Very.
Unlike any other member of the Geraniaceae I am familiar with, the fleshy twigs of Pelargonium carnosum can be “eaten as a snack“. This prompted me to question the edibility of the geranium family in general. I had a vague recollection that the petals and leaves of some of the scented-leaf pelargoniums could be eaten or used as flavouring, but I was also interested to learn that the roots of some Geraniaceae are also edible. Every year, the students in UBC’s Horticultural Training Program are assigned a project in which they have to document the plant families they ingest; I don’t think any of the students have yet submitted Geraniaceae.
