Yellow and golden like the spring sun. The Cowslip (Primula veris) also called common cowslip. The English name does not make it justice but it is often found in ground where cows graze. Think I like the Swedish name Gullviva better. Could be translated into spring gold.
My wife call them keys of may (I don’t really have the heart to tell her that there is a completely different flower with that name) as they starts to bloom in the first days of may. They appear in plenty in the fields around our house. Ha de Gött!
