Superscript, subscript, and greek symbol all in one axis title in ggplot2

I have the following title which I need for an axis for my plot in ggplot2:
Plant δ34S (%0).

I'm unsure how to format it so that it appears properly in this question, but I need the 34 as as a superscript and the zero as a subscript. Therefore, I need a greek symbol, a superscript, and a subscript all in one axis title.

Although I know of various ways to code using expression, bquote, paste, etc, I've had little luck incorporating all three of these special cases. Any tricks to coding this properly?

Try this:

plot(0, xlab = ~ paste("Plant ", delta ^ 34, "S ", ("%"[0])))
