As it turns out, my Geranium essential oil is actually, Rose Geranium.
A different sort of geranium but one I happen to have just outside my back door.
Once upon a time, I collected every variety I could find of the scented-leaf group of Pelargoniums. At the height of this craze, I had several varieties of Rose, Lemon, Lemon Rose, Peppermint, another sort of Mint, Nutmeg, Apple, and more. I particularly loved the delicate, light green Apple, and the velvety, broad leaf Peppermint. They were all highly susceptible to Aphids and I spent many hours making and spraying a soapy Cayenne Pepper mix. But the Aphids put up a mighty fight and never really went away.
