Have you ever misread a plant label?
My late mother was a superb gardener and knew a great deal about many plants. However she was rather stumped when she saw a pot full of Morning Glory (Ipomea) seedlings in my greenhouse and asked " what's this one pomea?" I have a little chuckle every time I see a Morning Glory now.
