Have you tried Google searches (i.e. Turnip Greens in Danish)? You could also try a great smartphone app for language translation, called 'Google Translate'. You can speak in a multitude of languages, and choose your output language. Some languages have audio output (Danish has audio), but you will get the written versions no matter the language.
If it helps, løvetann is Norwegian for dandelion. I know the two languages are very similar.
I've had a lot of luck finding the Norwegian word for plants by finding the Latin name and then googling that, which usually takes me to the Norwegian wikipedia which will give me the common name.
I’ve tried google translate and wikipedia and everything else I can think of. The reason I’m asking is because google translate isn’t always accurate and neither is wikipedia. I would just like know what it’s called, from a Danish person since they would know what I’m talking about
