三星蔥是台灣蔥種中，蔥白最長、纖維最細緻，擁有獨特的辣芳香及鮮甜的口感。

三星蔥生長於三星鄉宜蘭沖積扇平原的扇頂，潮濕多雨、水質清淨、土壤肥沃。蔥雖愛濕卻不耐水，這裡地表下的土石間隙大，利於排水。來自雪山山脈的西風，正好防止根部腐爛。

青蔥文化館利用在地優勢，秉持新鮮、創意、新風味，推廣三星蔥系列食品，成為具有宜蘭味的伴手禮。

Among all the species in Taiwan, Sanxing spring onion has the longest, and most delicate white part, giving it unique spicy fragrance and sweetness.

Sanxing spring onion grows in an area at the top of the alluvial fan in Yilan, with sufficient rain and moisture, clean water, and rich soil. Spring onion prefers wet surroundings, but rots easily in water. Here, the gaps between sand and rocks underneath the surface are large, and water drains easily. The west wind from Xueshan Mountain Range prevents the roots from rotting.
Spring Onion Museum utilizes local strengths to promote food products made of Sanxing spring onion, offering souvenirs with the most iconic Yilan flavor.
