Describe the Ewell "homestead."

Here is a quote:

One corner of the yard, though, bewildered Maycomb. Against the fence, in a line, were six chipped-enamel slop jars holding brilliant red geraniums, cared for as tenderly as if they belonged to Miss Maudie Atkinson, had Miss Maudie deigned to permit a geranium on her premises. People said they were Mayella Ewell’s. (Chapter 17)
