多年生草本。茎基粗壮，顶部具有宿存的卵状披针形鳞片，鳞片长约4毫米。茎多条并生，不分枝或下部分枝，被灰白色短柔毛。叶自茎下部而上稍有增大，互生，仅花下4或5枚叶子聚集呈轮生状；叶片卵状椭圆形，长4-6 (8) 毫米，宽1.5-4毫米，两面均被短柔毛，边缘反卷，有波状浅齿或近全缘，基部楔形，有短柄。花单生主茎和分枝的顶端，花梗长0.4-1.3厘米，生柔毛；花萼短筒状，花期稍下窄上宽，果期下宽上窄，密被倒伏刚毛以至无毛，筒长5-8毫米，裂片三角形，长2-3毫米，略超过宽，密生白色睫毛；花冠蓝紫色或深蓝色，为花萼长的2.5-3倍，外面无毛，内面喉部密生柔毛，裂片倒卵状长矩圆形，约占花冠长的2/5；子房在花期约与萼筒等长，花柱伸达花冠喉部。蒴果超出花萼。种子矩圆状，淡褐色。花期8-9月。
本种近光萼蓝钟花 C. leiocalyx, 但茎平卧，蔓生或上升，花萼多少被毛，极少无毛，叶片两面均生白色柔毛，但不倒生。
