Primrose

Littondale's thin limestone soils provide an increasingly rare and valuable habitat, supporting a variety of unusual plants. Skoska Wood is a National Nature Reserve between the villages of Arncliffe and Litton, a strip of ash woodland and herb-rich pasture.  To be honest, I don't know that much about wild plants and, generally speaking, I wouldn't recognise a rare plant if I saw one. Though they are not uncommon, I was thrilled to see banks of wild primroses (Primula Vulgaris), which are such a pretty, delicate, pale yellow. I didn't know, either, that there are two types of primrose flowers - pin flowers (shown) and thrum flowers, which have a sort of little coronet in the centre. Fertilisation can only occur between the two types (thanks Wikipedia!). You learn something every day.
