there are ~37 -esce verbs listed in OED online; some of these come with the usual OED caveat (i.e., those that have been obsolesced or are rarefied).

here's one:
frondesce - To put forth leaves.
.how cool is that?

and another:
rejuvenesce - To become young again; spec. in Biol. of cells: To acquire renewed vitality.
