Grimrose

Grimrose is the fifth and last plant obtained in Modern Day. It instantly kills the strongest zombie on the lane (but deals damage to Gargantuars and machines) by dragging it into the ground, regardless if it is behind or in front of this plant. When powered by Moonflower, it can attack three times before disappearing.

Origins
Grimrose is based on the Onagraceae a family of plants, known as Evening Primroses.

Almanac entry
Grimroses are shadow plants that behave like landbound Tangle Kelps, dragging zombies into the dirt.

Special: powered Grimroses can drag 3 zombies before expiring.

"When you think about it, the proper place for a zombie is in the ground," says Grimrose. "So, really, I'm just expediting the process."

Trivia

 * Grimrose is a portmanteau on "primrose" and "grim."
 * It may also be a pun for The Grimm Bros.
 * Grimrose's Almanac says "the proper place for a zombie is in the ground," alluding how zombies usually rise from tombstones or the ground.
 * Both of its costumes appear to be hats of some kind.
 * Its straw hat costume resembles the Asian conical hat, a type of conical hat.
 * Grimrose cannot kill zombies that are floating above the ground.
 * It can't grab Gargantuars, much like Tangle Kelps.
 * The number of times it can drag zombies is represented by the number of stamens on its head.
 * This is why powered Grimroses have three stamens but unpowered ones only have one.
 * However, Grimrose's seed packet shows an unpowered Grimrose with three stamens.
