My daughter bought this set at a yard sale years ago. There are no markings except for the design which looks to be hand painted. Does this look familiar to anyone?
Said to be from the 1960s. Note that the price ($59) includes two vases and a ginger jar in a matching pattern as well as the teapot. If our esteemed member @Yang Hao sees this post, he can probably tell you what the poem is.
