That's Pelargonium species, not Geranium ...

I got a question in my inbox: "Can any geranium leaves be used for herbal teas? Or is it only the rose geranium (Pelargonium capitatum)?"

You can use the leaf of all Pelargonium species for tea. Note, however, that the taste exactly like they smell ... I'd only use scented geraniums, and of those, only the ones I like. Like lemon and rose. Urk for pine, nutmeg and the like. Double, no, triple urk for the "pretty" pelargoniums - gak. Blearg.
