Mourning Glory

The Grain Grave is a plant that when planted, will release a new Plant every huge wave. It is unlocked on level 2-9 of Plants vs. Zombies 3: Escape From Zomboss. It is however, burnt by the Grain Buster.

Strategy
It is good to use them on levels with many huge waves, and protect them in Pumpkins, as then Grain Busters won't attack.

Almanac
Grain Grave

Grain Graves release new plants during huge waves.

Special: Releases Plants

People are scared by Grain Grave, most likely because he takes the parts of dead and rotting plants from underground, then stitches them together to create new plants. Who knows. He just likes keeping Plants alive.
