I always thought the wild primroses (Primula vulgaris) were pale yellow.
When I was a child and then a student of geology, I was used to see their yellow flowers in the green fields at the end of winter.

When I moved in the house where I live my father planted some wild primrose in my garden.
Every year I also like to plant some colored primrose along the alleyway. They are not wild primrose but cultivated species of different colors: violet, purple, yellow, red, white.

With passing time the wild primroses conquered a specific part of the garden. Some years ago I noted one of them that was of a different color, a light purple in the middle of pale yellow ones.
My first thought was that it was an hybrid: a wild plant had received the pollen from a cultivated one also receiving a different color.
By searching on the web I also found there are wild subspecies of different colour (purple, white, …) but they are not typical of Italy
I don’t care if the strange wild primroses of my garden are rare species or hybrids, but this year they decided to bring me a surprise. Strange coloured plants are numerous, with different tones of violet and rose.

We can call it the evolution, or may be it is only the Nature that likes to joke with colours.
