汴梁西瓜是开封的传统特产，驰名古今，畅销中外。其特点是：皮薄汁多，瓢沙脆甜，清利可口。民间素有"肖县石榴砀山梨，汴梁西瓜红到皮"之谚语。因开封古称"汴梁"，万事故开封一带生产的西瓜都叫"汴梁西瓜"。
      
    西瓜原产于非洲热带沙漠地区，有四千多年的种植历史。约于公元十世纪（五代十国时期）由西域移植我国，先在回鹘（现新疆境风）栽培，后传入内地，因瓜种来自我国西部，故名西瓜。
      
    西瓜双名寒瓜，为葫芦科一年后草本植物。西瓜不仅是盛夏消暑解渴之上乘佳品，更兼有多种用途。其瓢、皮、籽均可入药，有消烦止渴，解暑热，宽中下气，利小水，治血痢，解酒毒，治口疮，清肺润肠，补中宜人之医疗功用。西瓜皮还能做菜。
      
    汴梁西瓜在北宋种植已很普遍，在张择端的《清明上河图》上就有表现。开封一带气候温和，夏季雨水均匀，沙壤土质较多，适宜西瓜的增长。加之开封人民长期以来积累丰富的西瓜种植经验，把西瓜作为乡土珍品精心种植，不断改进，使开封西瓜逐渐成为中州著名的特产。
