The three sets of Post & Go stamps being issued in 2014 will celebrate UK wild flowers and plants. The species selected for the series include some that are associated with the national flowers of the countries in the UK – the daffodil, thistle, rose and flax for Wales, Scotland, England and Northern Ireland respectively.

Springtime flowers mark the most profound change from the chilled depths of winter to the rebirth of spring. Every year, no matter how harsh the winter, spring flowers appear, sometimes peeking through the snow, reminding us that a new season beckons. As well as being a source of great joy and injecting colour into the countryside, these plants are vital sources of food for animals that hibernate over winter in the UK. Sadly, each year many of these species are reducing in number, victims of changing weather and competition from more common species which thrive in polluted ecosystems. You can help rare plants by reducing your impact on the planet and joining a conservation organization with a mission to protect them.
