Many things around us are representative of the phallus or the chalice. I wonder if anyone here is an expert.
Far too many people want to see representations or similarities in lots of things. Freud took it to ludicrous lengths by couching such things in long words and made-up "systems". But it's the universal human propensity not just to see, but to seek out, patterns and similarities in all kinds of things.
Ancient herbal theory 'works' on this basis. 'Lungwort' is named, not for its observed efficacy in dealing with respiratory illnesses, but because of the similarity of the leaves to lung tissue. Even if were shown to be helpful for lung problems, it would
not be because of its visual appearance. It would be mere chance. 'Mandrake' was named because the oddly shaped roots look, to the imaginative eye, a bit like the limbs of a human. It's only "medical" use was as a narcotic.
There are a few that are named for genuine efficacy. Comfrey, for instance, is commonly known as 'knitbone'. It is very efficacious as an external poultice for bruises, sprains and minor breaks.
For sexual imagery, anyone who wants to can see phallic or female sexual likenesses in the natural or built world can find them anywhere and everywhere. Just look at a basket of a dozen different vegetables - once you're inclined to look at stuff through this distorting lens, you'll see what you're looking for all over the place.
