Homing Thistle

Homing Thistle is a premium plant that was released in the 2.9.1 update of Plants vs. Zombies 2: It's About Time. It attacks similarly to the Cattail. Its spikes deal two normal damage shots each.

Almanac entry
DAMAGE: Moderate

Homing Thistles fire seeking shots at targets that are closest to home.

Don't even think about trying to pull one over on Homing Thistle. He's got a bead on you. He sees right through your facade. It's like he has a laser beam...aimed at your soul.

Plant Food upgrade
When given Plant Food, Homing Thistle shoots many glowing blue projectiles that target zombies on the screen, or tombstones, if there are not enough zombies. The blue projectiles do more damage than normal ones, and they sometimes encircle zombies for a long period of time.
