I bought this plant in the bedding plants section of a nursery the other day, the tag simply reads "Yellow Portugal - Bushy plants with bright yellow daisy-like flowers. Full sun. Use in hanging baskets and planters" - I'm trying to read up on it online, but I can't find any reference to a flower called "Yellow Portugal" - does anyone recognize this and know another name for it, preferably the Latin? The flowers are about 2cm wide. Thank you!
Taking Andrey's suggestion, I see that Lysimachia nemorum is called "Yellow Pimpernel". Does "Pimpernel" sound like "Portugal"? It looks a lot like your photo, see photo on a medicinal herbs website. And Lysimachia nemorum ssp. azorica is pictured on a Portuguese stamp. Maybe that's the connection? The Azores are a Portuguese archipelago.
Thanks you two! That sure looks like the same plant to me, mystery solved? Thanks so much!! Wendy - Yes I could see someone perhaps getting "Pimpernel" mixed up with "Portugal", I bet that's what happened.
I think the connection is more likely the Azores and the flower on the stamp. Or I'd like to think so!
When I Google yellow portugal the only relevant hit (on the first page of results, anyway) is this thread. I am sure it is a mistake for yellow pimpernel, all it takes is somebody squinting at faded text and making the wrong conclusion about what a word is supposed to be.
