Garlic is VITAL for most Last Stand Strategies in order to save sun by defending less rows. The Garlic is also useful when using Gloom-shrooms or (for those who use them, not me) Starfruit or even Threepeaters.

The only places I find it useless are Survival: Endless (too many Zombies to overpower it) and Zombotany/Zombotany 2. I find it very useful in Seeing Stars as well, in a Gloom-shroom Strategy.
