Flower Friday - Petrklic

Apart from snowdrops there are still no flowers to be seen yet. On Monday it's my husband's name day and his name is Petr so I bought him a pot of primroses. They are called Petrklic in Czech meaning Petr's key - clavis sancti Petri in Latin unlocking the door to spring.

It's a new thing for me to take flower photos in mono.

Many thanks to BikerBear for hosting the Flower Friday challenge.
