I'm not sure what you're asking for.

You can use VertexRenderingFunction to design how the vertexes are
displayed.

vertex[pt : {x_, y_}, tag_, index_] :=
  Text[ToString[tag] <> " (" <> ToString@Head[tag] <> ")", pt];

TreePlot[
 {1 -> a, 1 -> 2, 2 -> "apple", a -> 7, 2 -> "log", a -> "six",
  1 -> "A", "A" -> four, "A" -> Log},
 VertexLabeling -> True,
 VertexRenderingFunction -> vertex
 ]
