These flowers with their unusual colour combination I saw the other day grow on a plant called bittersweet (Solanum dulcamara), bitterzoet in Dutch:
Olympus Stylus 1s, 42mm, ISO200, f8, 1/60s
The books say that the plant tastes bitter at first, and then sweet. I wonder how people found out, as parts of this plant are a bit toxic, like many of the nightshades are. Yes, still talking about this plant.
