Yes. The edible leaves and flowers of Geranimun are used as a flavouring in desserts, cakes, jellies and teas. Also Geranimun or Pelargonium distillates and absolutes, commonly known as "scented geranium oil" are sometimes used to supplement or adulterate expensive rose oils.
I think it depends on whether you are referring to pelargoniums, which many people call geraniums, or if you're referring to real geraniums. I'm not sure about the edibility of one or the other, there are some cook books available. I think the stink of pelargoniums would put off anyone from eating them.
Check first, from a reliable source, not a bunch of amateurs on here who can say anything.
