The "gaudy melon-flower," Browning's synecdoche for the Other, seems to represent the southern Mediterranean, or indeed anywhere further south than England, given that melons need warm temperatures to grow. In this disparaged aesthetics of the familiar, however, the larger, brighter, yellower melon-flower ceases to be luminous in comparison with the common, small, less yellowy, and yet unavailable English buttercup. 
What does the "gaudy melon" flower in Robert Browning's "Home Thoughts, from Abroad" symbolize?
It symbolizes the springtime scene and the blooming of flowers.

I hope it helps, Regards.
