Which floral emblem is associated with Northern Ireland?

The shamrock is the floral emblem associated with Northern Ireland, and its roots run deep into Irish history and culture. The shamrock, a small clover-like plant, is strongly associated with Saint Patrick, the patron saint of Ireland. Legend has it that Saint Patrick used the three leaves of the shamrock to explain the Holy Trinity – the Father, the Son, and the Holy Spirit – to the pagan Irish people during his mission in the 5th century. Because of this religious significance and its association with Saint Patrick, the shamrock became a symbol of Irish identity and pride. While Northern Ireland is part of the United Kingdom, it shares a strong cultural heritage with the rest of Ireland, and the shamrock remains a widely recognized and cherished symbol there. The other options are incorrect because the daffodil is the emblem of Wales, the thistle represents Scotland, and the rose is the emblem of England.
