What's the national flower of Northern Ireland?

The shamrock, a small clover-like plant, holds a special place in Irish culture and 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. This made the shamrock a powerful symbol of Christianity and Irish identity. While Northern Ireland is part of the United Kingdom, it shares a strong cultural heritage with the Republic of Ireland. Because of this shared heritage and the enduring legend of Saint Patrick, the shamrock is widely recognised and accepted as the national flower of Northern Ireland, representing its Irish roots and cultural identity. The lily, while beautiful, is not specifically tied to Northern Ireland. The thistle is the national flower of Scotland, and the rose is the national flower of England, making them incorrect choices for Northern Ireland.
