Columbine (Aquilegia vulgaris) is a superhydrophobic plant that is known to be resistant to snail attacks. On the other hand Hostas, which are also superhydrophobic, are often eaten.

It would be interesting to set up an experiment to see what happens under snail attack. The surface structure is much the same as that of the Cabbage family, as can be seen in the Scanning Electron Micrograph (SEM) picture below.
