每年四五月桐花開之時，到客家庄賞桐花已成為許多人不可或缺的休閒活動之一。賞桐花不僅是臺灣每年最盛大的賞花活動之一，同時也是接觸客家文化最重要的時節之一。走進客家村鎮，琳瑯滿目的客家商品和桐花一樣吸引遊客，這些商品多以桐花圖像做裝飾，以訴求其為客家商品，桐花圖像儼然已成為客家意象最具代表性的圖像。對這結果許多人不僅疑惑、憂心，甚至質疑其適切性。這是一個重要且嚴肅的設計議題，深入而嚴謹的研究有助於解開這個疑惑，此亦是本研究主要探索的內涵。首先從歷史發展的角度，探討臺灣桐樹栽植的範圍是否與客家族群分布的區域吻合，桐花與客家意象是如何接合與深化的過程等主、客觀因素；繼之從桐花的造形結構與色彩表現，評析與客家族群特質是否契合；再擇檢視現有以桐花圖像做為客家意象的各領域設計作品表現，探討其彈性與效果；最後透過綜合評析的方式，瞭解桐花圖像的成就與省思。研究結果顯示，桐花與客家族群的地緣性高，桐花圖像與客家族群特質的契合度也足夠，短期發展下，桐花圖像仍是代表客家意象最適切的一個圖像選擇，長期發展而論，應適當發揮不同客家意象視覺圖像的特性與功能。
