Mint?

[The Velveteen Ocelot]

10. You'll be exchanging one problem for another.

Mint is extremely invasive and before long it will have taken over. You might try planting catnip, which is also a member of the mint family and spreads readily, but it also attracts cats, who eat rabbits. The cats will be stoned and probably won't do much besides lie in the garden muttering, "Dude, have you ever really looked at your paw?" but the rabbits might decide to avoid them anyhow.
